[ Introduction ]

I'd like to walk you through the complete process of creating an up-to-date open-source server for Ragnarok Online using rAthena. This includes removing all of its security so that it can be accessed via multiple clients. Next, we'll install a web management control panel that users can create accounts on, submit tickets with, even research your servers’ unique stats and databases. Afterwards we're going to transform the latest official Korean client by diffing, hexing, translating, & heavily customizing it. Finally, we're going to configure the OpenKore client to work with our server. As well support interfacing with the official client through proxy.

We're going to be using the same packet structure across all aspects so that they can properly communicate with each other. This was selected by researching what the last fully developed version was for OpenKore. (2020-04-01b) Since this is running primarily open-source software, it slowly gets better overtime. This is actually ahead of the International Servers and many other countries not only in features but content. I've included the full process so that anyone can take the next or a different set of packets and reproduce these results. This is also completely portable. Ends with one folder, drag and drop. All software included is free, there is zero piracy endorsed.

[ Microsoft Visual Studio 2022: Installation ] [ 7.62GB ]

01.) Execute "VisualStudioSetup.exe". (let it update)
02.) At the install screen, scroll down to the "Desktop & Mobile" section.
03.) Checkmark "Desktop development with C++".
04.) Then look on the right side under "Installation details", go to the "Optional" section.
05.) Uncheck "Just-In-Time debugger". (this will remove Live Share as well)
06.) Uncheck "C++ profiling tools".
07.) Uncheck "C++ CMake tools for Windows".
08.) Uncheck "C++ ATL for latest v143 build tools (x86 x64)".
09.) Uncheck "Test Adapter for Boost.Test".
10.) Uncheck "Test Adapter for Google Test".
11.) Uncheck "IntelliCode".
12.) Uncheck "C++ AddressSanitizer".
13.) Click Install. (in bottom right)

Note: Wow! Even stripped down, this is a massive 7.62GB installation. Depending on how you access the internet this might take a while. Also, consider how far into the future you are from the time of this post. The install size will be different given it's continually updated. Feel free to move on while this is running in the background. You won't actually need to compile anything until you reach Step 14 of the rAthena section.

14.) Install Notepad++ (execute npp.8.3.2.Installer.x64)

Note: Moving forward, I highly suggest using Notepad++ to create and edit files. Primarily so you can get a line count without needing to boot all of Visual Studio. This is a clean and lightweight solution.


[ Laragon: Installing and Upgrading ]

01.) Extract Laragon Portable.
02.) Delete "php-5.4.9-nts-Win32-VC9-x86" from "laragon\bin\php".
03.) Extract "php-7.4.28-nts-Win32-vc15-x64" as a folder into "\laragon\bin\php".
04.) Delete "mysql-5.1.72-win32" from "laragon\bin\mysql".
05.) Extract "mariadb-10.7.3-winx64" as a folder into "\laragon\bin\mysql".
06.) Delete "nginx-1.14.0" from "laragon\bin\nginx".
07.) Extract "nginx-1.21.6" as a folder into "\laragon\bin\nginx".
08.) Delete all the contents of "\laragon\bin\heidisql".
09.) Extract "HeidiSQL_11.3_64_Portable" directly into "\laragon\bin\heidisql".
10.) Open Laragon. Click Start All.
11.) Grant MariaDB and Nginx firewall permissions when prompted.
12.) Close Laragon window, do not exit the program. Don't worry it's still running in your system tray.


[ rAthena: Installing, Configuring, and Optimizing ]

01.) Extract rAthena.
02.) Go to "\rathena\conf". Rename the "import-tmpl" folder to "import".
03.) Open: "\rathena\conf\import\char_conf.txt", add:

Code: Select all

// Server Communication username and password.
userid: supercool
passwd: coolsuper

server_name: GoblinRO

// Login Server IP
// The character server connects to the login server using this IP address.
// NOTE: This is useful when you are running behind a firewall or are on
// a machine with multiple interfaces.
login_ip: 127.0.0.1

// Character Server IP
// The IP address which clients will use to connect.
// Set this to what your server's public IP address is.
char_ip: 192.168.1.130

// Starting point for new characters.
start_point: iz_int,18,26

// Amount of time in seconds by which the character deletion is delayed.
char_del_delay: 10

// Restrict character deletion by email address or birthdate.
char_del_option: 1

// Restrict character deletion as long as he is still in a party or guild.
char_del_restriction: 0

// Pincode system
pincode_enabled: no
Note: You're going to want to enter your own userid/passwd, server name, and server IP. (wan if going off network)

04.) Open: "\rathena\conf\import\inter_conf.txt", add: "use_sql_db: yes"
05.) Open: "\rathena\conf\import\log_conf.txt", add:

Code: Select all

// log_filter: 1 = logs ANY items
log_filter: 1

// log_chat: 63 = logs everything
log_chat: 63
06.) Open: "\rathena\conf\import\login_conf.txt", add:

Code: Select all

// Can you use _M/_F to make new accounts on the server?
// Note: This only works if client side password encryption is not enabled.
new_account: yes

// Ipban features
ipban_enable: no
07.) Open: "\rathena\conf\import\map_conf.txt", add:

Code: Select all

// Server Communication username and password.
userid: supercool
passwd: coolsuper

// Character Server IP
// The map server connects to the character server using this IP address.
// NOTE: This is useful when you are running behind a firewall or are on
// a machine with multiple interfaces.
char_ip: 127.0.0.1

// Map Server IP
// The IP address which clients will use to connect.
// Set this to what your server's public IP address is.
map_ip: 192.168.1.130
Note: You're going to want to enter the same userid/passwd and IP used in char_conf.txt.

08.) Open: "\rathena\conf\import\packet_conf.txt", add:

Code: Select all

// IP rules
//   allow : Accepts connections from the ip range (even if flagged as DDoS)

allow: 127.0.0.1
allow: 192.168.0.0/16
Note: Change to match your network setup.

09.) Open: "\rathena\src\config\packets.hpp". Comment out lines: 44-62. (packet obfuscation)
10.) Open: "\rathena\src\custom\defines_pre.hpp". Line 12 add: "#define PACKETVER 20200401".
11.) Open: "\rathena\npc\re\warps\cities\izlude.txt". Comment out lines: 39-54.
12.) Open: "\rathena\npc\re\warps\fields\prontera_fild.txt". Comment out lines: 94-113.

Note: Why are removing these warps important? So these are the novice start areas to the game. Like any MMORPG these were the most populated maps 24/7/365. It got to the point where they became overflooded not just by new players but bots. You'd wonder around trying to find something to kill that wasn't already taken, to the point leveling actually became a nightmare. So what they did was implement multiple instances of the same maps. Putting players in different load balanced instances allowed everybody to breath and comfortably start the game with some people but not to many.

Though this had some downsides. Let's say you just started new characters so you could play with your friends. You might be loaded into prt_fild08a while your friends were loaded into b and c. Meaning there is zero crossover, you're all in your own unique world. You can't see each other, the monsters spawn differently, and that fun starting the game together experience is gone. Given we're setting up a small server here, there is no point in having multiple instances. So we're removing the extras and specifying a singular starting area.

13.) Create a new "compile.bat" file inside "\rathena" that contains:

Code: Select all

@echo off
"C:\Program Files\Microsoft Visual Studio\2022\Community\Msbuild\Current\Bin\MSBuild.exe" -m
pause
Note: Your install location might be different. Adjust accordingly.

14.) Execute compile.bat. Wait for it to finish. Check to make sure it's error free at the end.
15.) Convert all data files to SQL so you can use MariaDB via running "\rathena\yaml2sql.bat". (you will have to confirm with "Y" ten times during this process)
16.) Open "\rathena\sql-files", delete the following:

Code: Select all

item_db.sql
item_db_equip.sql
item_db_etc.sql
item_db_usable.sql
item_db2.sql
mob_db.sql
mob_db2.sql
mob_skill_db.sql
mob_skill_db2.sql
readme.md
17.) Open "\rathena\sql-files\compatibility" and move "item_db_re_compat.sql" and "item_db2_re_compat.sql" up one level to "\rathena\sql-files". You should now have 16 files (not including folders) inside "\rathena\sql-files".
18.) Open Laragon. Click Database. Click New. (bottom left)
19.) Under "Session Name", change "Unnamed" to "Laragon". Then click "Open".
20.) Click "manage user authentication and privileges" in the top bar.
21.) Click "Add". Change username to "ragnarok". Change password to "ragnarok". Checkmark the "Global Privileges" box. Click Save. Click Close.
22.) Right click "Laragon" in the top of the left column. Expand "Create new". Click "Database". Enter name "ragnarok". Click OK.
23.) Click "ragnarok" in the left column. Go to "File" in the top left. Expand and click "Run SQL File". Direct to "\rathena\sql-files\". Select all 16 .sql files. Click Open. Confirm auto-detect. (let finish)
24.) Click "refresh" in the top bar. (next to manage user authentication and privileges)
25.) Expand the "ragnarok" database in the left column. Click "login" which will bring it up on the right. Click the "data" tab.
26.) Change the account's userid and user_pass to match the server communication username and password created back in step 3.
27.) Close these windows. Get back to having Laragon running in your system tray.
28.) Open "kRO_FullClient_20210406.zip", extract "msvcr110.dll" into "\rathena".
29.) Go to "\rathena", execute "runserver.bat". Three consoles: the login, character, and map servers are going to open.
30.) As each part comes online you'll need to grant it firewall access.

Note: We're spinning up the server to make sure we're good before moving on. You should see all green status updates.

Note: If you plan on including WAN clients, then you'll need to open the: 5121, 6121, 6900, & 80 ports on your network firewall / router. Please consider this a large security risk! The scope of this document does not include properly securing an exposed server. Proceed with caution.


[ Flux Control Panel: Installing and Modifying ]

Using wrong servertype in clientinfo/sclientinfo xml. Please change servertype to correct one.
Note: You'll notice how two of them don't ask for a file extension, which is why we leave it off. That is not erroneous.

15.) You should have 70 enabled patches when finished. Click "Apply Selected". Close Nemo.
16.) Clean up the "\client" directory by deleting the following no longer required files:

Code: Select all

\AI_sakray

Note: This should leave you with 58 files inside "\client". (8 folders + 50 misc)

17.) Go to "\client\data". Open "clientinfo.xml". Change it too:

Code: Select all

<?xml version="1.0" encoding="euc-kr" ?>
<clientinfo>
	<desc>Ragnarok Client Information</desc>
	<servicetype>korea</servicetype>
	<servertype>primary</servertype>
	<connection>
		<display>GoblinRO</display>
      		<address>192.168.1.130</address>
      		<port>6900</port>
      		<version>55</version>
      		<langtype>0</langtype>
   	</connection>
	<connection>
		<display>OpenKore</display>
      		<address>127.0.0.1</address>
      		<port>6901</port>
      		<version>55</version>
      		<langtype>0</langtype>
   	</connection>
</clientinfo>
Note: Inside the first <connection> block, change the <display> name and <address> to match your server. If WAN, you can use services like No-IP.

18.) Go to "\client". Execute "opensetup.exe". (decline Telemetry prompt) Change the options to match your wants and needs. (graphics device, resolution, etc)

Note: I personally like 1280x720 when playing in a window. Specifically while using X-Kore which we'll cover later.


[ The OpenKore Client: Packet Extraction, Configuration, and Field Updating ] [ Best Client ]

Note: Steps 1 and 2 are educational. Worth learning but can be skipped as I've already done this for you.

01.) Extract Winsock Packet Editor (WPE). Allow the executable if Windows Defender or your anti-virus software flags it.
02.) Using "WPE PRO - modified.exe" follow the Openkore Wiki Connectivity Guide to obtain master version and version number. (screenshot)
03.) Extract OpenKore.
04.) Go to "\openkore\tables" then open "servers.txt". Find "[Localhost]" towards the bottom. Replace with:

Code: Select all

[Localhost]
ip 192.168.1.130
port 6900
private 1
master_version 0
version 128
charBlockSize 155
serverType kRO_RagexeRE_2020_04_01b
serverEncoding Western
addTableFolders kRO/RagexeRE_2020_04_01b;translated/kRO_english;kRO
Note: Change the IP address to match your server. If WAN, you can use services like No-IP.

05.) Go to "\openkore\fields". You'll notice inside are a number of folders labelled by episode number. You're going to want to take all the files out of each of these episodic folders and move them up a directory. Overriding the ones currently in your "\openkore\fields" folder.

Note: We're doing this so that the bot can understand the map layouts of the newer content. The rAthena emulator is always improving but currently at the time of posting goes all the way to Episode 18. You might notice the bot is currently only developed up to Episode 17.1. If you play that far then you'll probably have a good idea on making the bot work in uncharted waters. For now, don't worry about it one bit. You're good for a loooooong time. Hell they'll probably have it included by the time you make it there.


[ Logging Into Your Server, Making a GM Account, and Playing! ]

Note: Even if you want to go straight to using OpenKore, we're going to use the kRO client to finish off the server and make our first accounts. While these steps can be done in OpenKore, it's easier to just follow along using a visual interface for now. If you've picked this project up at a later date, then make sure you've started the rAthena servers. (go to "\rathena", execute "runserver.bat")

Using the kRO Client:
01.) Go to "\client" and execute "2020-04-01bRagexe_patched.exe".
02.) Select "GoblinRO" when prompted. (the server name you entered previously)
03.) At the login screen type "admin_M" to make a new account on the server. You need to enter a 6+ digit password as well. (123456)

Note: The first account is always a GM account. This has a different set of sprites used that are not compatible with actually wanting to play the game. They look cool because on the off chance you actually crossed one it needed to be unique. Generally you only saw one if you were about to get banned for botting or hacking so it was quite the event to casually see an admin. LOL!

04.) Make a new character you're going to use to pwn rule breakers. Once in game, hit escape, then click "exit to windows".
05.) Open Laragon. Click Database. Click "Open" in the new window.
06.) Expand the "ragnarok" database. Click "login" again like we did in Step 25 of setting up rAthena. Click the "data" tab.
07.) Look for the newly created admin account under the server account. Change it's "group_id" to 99. (now has full GM powers)
08.) Close these windows. Go back to having Laragon running in your system tray.
09.) Once again head to "\client" and execute "2020-04-01bRagexe_patched.exe".
10.) At the login screen let's make a real account to actually play on. Once again, "yourname_M" or "yourname_F" (male or female) to make a new account on the server.

Note: The sex you select here is only used for account management and does not effect the sex of your characters you make in game. It's pretty much pointless.

11.) Spend extra time picking the right hair style, color, sex, and race. This is your new character!!
12.) Play the game!

Note: Future logins do not require the _M or _F after your account name. This is only done the first time to register a new account on the server from inside the client. You can also register accounts with the Flux Control Panel if you like. If you ever want to delete a character, it'll ask you for your email address as a security check to confirm. Accounts created in client automatically get registered with "a@a.com" as their email address in the database.

Using the OpenKore Client:
01.) Go to "\openkore\control". Open "config.txt".
02.) Line 6: add "Localhost".
03.) Line 7: add "0".
04.) Line 8: add "Goblin". (your username) (do not add _M or _F)
05.) Line 9: add "123456". (your password)
06.) Line 11: add "0". (number / position of your character)
07.) Save file.
08.) Go to "\openkore" and execute "wxstart.exe". (wait for it to process maps and finish loading)
09.) Play the game!

Note: OpenKore does not currently support the new character start maps. It'll just throw errors in the console about not being able to navigate. Use the kRO client to at least get out of the introduction area. You can walk directly through the beginning and board the ship to Izlude. It's not required to interact with anything if you don't want to. There is stuff to do though, up to you.

Using OpenKore inside kRO via X-Kore:
01.) Go to "\openkore\control". Open "config.txt".
02.) Line 23: change "0" to "3".
03.) Line 30: change "ragexe.exe" to "2020-04-01bRagexe_patched".
04.) Save file.
05.) Go to "\openkore" and execute "wxstart.exe". (wait for it to finish loading)
06.) Go to "\client" and execute "2020-04-01bRagexe_patched.exe".
07.) Select "OpenKore" when prompted.
08.) Login via your normal username and password for the account.
09.) Select your character at the next screen.
10.) Play the game with two clients at once!

Note: I highly suggest running kRO in windowed mode for ease of use. This way you can bounce back and forth between the clients effortlessly. You do not need to keep the kRO or OpenKore windows as a focused priority. You can literally open other applications on top of both without any pause to the botting. You'll hear it in the background still playing the game while you're reading the wiki, checking email, or just doing whatever you please.


[ Troubleshooting The Situation ]

Note: Having an odd problem loading software at any point? Getting an error and not sure why? I'm not sure why either so give this a whirl.

01.) Extract "Visual-C-Runtimes-All-in-One-Feb-2022.zip"
02.) Execute "install_all.bat".
03.) Wait for it to finish.
04.) ??? Try Again ???
05.) Probably Success.


[ Packaging It Up For Transportation ]

01.) Make a new folder called "GoblinRO". (or whatever you like)
02.) Place your "\laragon", "\rathena", "\client", & "\openkore" folders inside it.
03.) Make a new folder inside called "troubleshooting".
04.) Copy "Visual-C-Runtimes-All-in-One-Feb-2022.zip" into "\troubleshooting".
05.) Compress your "GoblinRO" folder. (zip/rar)

Note: Transportation or not, I suggest you make a backup like this once you're finished. Always a good idea! Also compressing it greatly helps transfer times to things like USB drives or across networks. Not only is the file size reduced from around 5.5GB to 3.9GB but the fact that it doesn't have to work with the insane amount of small files present is a life saver. Remember you can always just extract the /client or /openkore folder if you're on computers that aren't running the server.


[ Post Install House Cleaning ]

01.) Delete the Master List of downloaded files required for install. (18 files, 3.8GB)
02.) Uninstall Microsoft Visual Studio 2022 Community Edition. (7.62GB)

Note: You will lose your ability to compile the server again if you make future changes.


[ Conclusion ]

Alright! Way to make it to the end! I spent a week constructing this. Across that time, I reached out to a lot of the related discord servers and forums. Mainly making sure my instructions were correct and up to date. At most stops I was met with silence then a private message with a price tag. Anywhere from $10-100 an hour, just for their working knowledge of an old MMORPG. For truly custom work I do understand it, but for basics? It really only motivated me more to put this out.

I'd like to help remove the ridiculous paywall that has slowly started to surround this information. Sure, this has been a deep dive into an esoteric world. This game is over twenty years old at this point. Though it saddens me to see information omitted or even removed in order to sell it back to people as a service. I think that's not only harmful but gating something we have all enjoyed for decades. This is just information, there is nothing deserving of your currency. Everyone should be able to do this, for free.

I hope you have found this both helpful and educational! Feel free to translate into your local language and distribute. I have done three trial runs across different machines and have not had a problem. If you're experiencing issues check that you haven't missed a step. Need support? Check the forum, wiki, github, and discord for both rAthena and OpenKore. Still can't find a solution? Post here! I cannot guarantee a timely response but I will check back in occasionally and try to help out as much as I can. Thanks for reading! /cheers

[ Introduction ]

I'd like to walk you through the complete process of creating an up-to-date open-source server for Ragnarok Online using rAthena. This includes removing all of its security so that it can be accessed via multiple clients. Next, we'll install a web management control panel that users can create accounts on, submit tickets with, even research your servers’ unique stats and databases. Afterwards we're going to transform the latest official Korean client by diffing, hexing, translating, & heavily customizing it. Finally, we're going to configure the OpenKore client to work with our server. As well support interfacing with the official client through proxy.

We're going to be using the same packet structure across all aspects so that they can properly communicate with each other. This was selected by researching what the last fully developed version was for OpenKore. (2020-04-01b) Since this is running primarily open-source software, it slowly gets better overtime. This is actually ahead of the International Servers and many other countries not only in features but content. I've included the full process so that anyone can take the next or a different set of packets and reproduce these results. This is also completely portable. Ends with one folder, drag and drop. All software included is free, there is zero piracy endorsed.

[ Microsoft Visual Studio 2022: Installation ] [ 7.62GB ]

01.) Execute "VisualStudioSetup.exe". (let it update)
02.) At the install screen, scroll down to the "Desktop & Mobile" section.
03.) Checkmark "Desktop development with C++".
04.) Then look on the right side under "Installation details", go to the "Optional" section.
05.) Uncheck "Just-In-Time debugger". (this will remove Live Share as well)
06.) Uncheck "C++ profiling tools".
07.) Uncheck "C++ CMake tools for Windows".
08.) Uncheck "C++ ATL for latest v143 build tools (x86 x64)".
09.) Uncheck "Test Adapter for Boost.Test".
10.) Uncheck "Test Adapter for Google Test".
11.) Uncheck "IntelliCode".
12.) Uncheck "C++ AddressSanitizer".
13.) Click Install. (in bottom right)

Note: Wow! Even stripped down, this is a massive 7.62GB installation. Depending on how you access the internet this might take a while. Also, consider how far into the future you are from the time of this post. The install size will be different given it's continually updated. Feel free to move on while this is running in the background. You won't actually need to compile anything until you reach Step 14 of the rAthena section.

14.) Install Notepad++ (execute npp.8.3.2.Installer.x64)

Note: Moving forward, I highly suggest using Notepad++ to create and edit files. Primarily so you can get a line count without needing to boot all of Visual Studio. This is a clean and lightweight solution.


[ Laragon: Installing and Upgrading ]

01.) Extract Laragon Portable.
02.) Delete "php-5.4.9-nts-Win32-VC9-x86" from "laragon\bin\php".
03.) Extract "php-7.4.28-nts-Win32-vc15-x64" as a folder into "\laragon\bin\php".
04.) Delete "mysql-5.1.72-win32" from "laragon\bin\mysql".
05.) Extract "mariadb-10.7.3-winx64" as a folder into "\laragon\bin\mysql".
06.) Delete "nginx-1.14.0" from "laragon\bin\nginx".
07.) Extract "nginx-1.21.6" as a folder into "\laragon\bin\nginx".
08.) Delete all the contents of "\laragon\bin\heidisql".
09.) Extract "HeidiSQL_11.3_64_Portable" directly into "\laragon\bin\heidisql".
10.) Open Laragon. Click Start All.
11.) Grant MariaDB and Nginx firewall permissions when prompted.
12.) Close Laragon window, do not exit the program. Don't worry it's still running in your system tray.


[ rAthena: Installing, Configuring, and Optimizing ]

01.) Extract rAthena.
02.) Go to "\rathena\conf". Rename the "import-tmpl" folder to "import".
03.) Open: "\rathena\conf\import\char_conf.txt", add:

Code: Select all

// Server Communication username and password.
userid: supercool
passwd: coolsuper

server_name: GoblinRO

// Login Server IP
// The character server connects to the login server using this IP address.
// NOTE: This is useful when you are running behind a firewall or are on
// a machine with multiple interfaces.
login_ip: 127.0.0.1

// Character Server IP
// The IP address which clients will use to connect.
// Set this to what your server's public IP address is.
char_ip: 192.168.1.130

// Starting point for new characters.
start_point: iz_int,18,26

// Amount of time in seconds by which the character deletion is delayed.
char_del_delay: 10

// Restrict character deletion by email address or birthdate.
char_del_option: 1

// Restrict character deletion as long as he is still in a party or guild.
char_del_restriction: 0

// Pincode system
pincode_enabled: no
Note: You're going to want to enter your own userid/passwd, server name, and server IP. (wan if going off network)

04.) Open: "\rathena\conf\import\inter_conf.txt", add: "use_sql_db: yes"
05.) Open: "\rathena\conf\import\log_conf.txt", add:

Code: Select all

// log_filter: 1 = logs ANY items
log_filter: 1

// log_chat: 63 = logs everything
log_chat: 63
06.) Open: "\rathena\conf\import\login_conf.txt", add:

Code: Select all

// Can you use _M/_F to make new accounts on the server?
// Note: This only works if client side password encryption is not enabled.
new_account: yes

// Ipban features
ipban_enable: no
07.) Open: "\rathena\conf\import\map_conf.txt", add:

Code: Select all

// Server Communication username and password.
userid: supercool
passwd: coolsuper

// Character Server IP
// The map server connects to the character server using this IP address.
// NOTE: This is useful when you are running behind a firewall or are on
// a machine with multiple interfaces.
char_ip: 127.0.0.1

// Map Server IP
// The IP address which clients will use to connect.
// Set this to what your server's public IP address is.
map_ip: 192.168.1.130
Note: You're going to want to enter the same userid/passwd and IP used in char_conf.txt.

08.) Open: "\rathena\conf\import\packet_conf.txt", add:

Code: Select all

// IP rules
//   allow : Accepts connections from the ip range (even if flagged as DDoS)

allow: 127.0.0.1
allow: 192.168.0.0/16
Note: Change to match your network setup.

09.) Open: "\rathena\src\config\packets.hpp". Comment out lines: 44-62. (packet obfuscation)
10.) Open: "\rathena\src\custom\defines_pre.hpp". Line 12 add: "#define PACKETVER 20200401".
11.) Open: "\rathena\npc\re\warps\cities\izlude.txt". Comment out lines: 39-54.
12.) Open: "\rathena\npc\re\warps\fields\prontera_fild.txt". Comment out lines: 94-113.

Note: Why are removing these warps important? So these are the novice start areas to the game. Like any MMORPG these were the most populated maps 24/7/365. It got to the point where they became overflooded not just by new players but bots. You'd wonder around trying to find something to kill that wasn't already taken, to the point leveling actually became a nightmare. So what they did was implement multiple instances of the same maps. Putting players in different load balanced instances allowed everybody to breath and comfortably start the game with some people but not to many.

Though this had some downsides. Let's say you just started new characters so you could play with your friends. You might be loaded into prt_fild08a while your friends were loaded into b and c. Meaning there is zero crossover, you're all in your own unique world. You can't see each other, the monsters spawn differently, and that fun starting the game together experience is gone. Given we're setting up a small server here, there is no point in having multiple instances. So we're removing the extras and specifying a singular starting area.

13.) Create a new "compile.bat" file inside "\rathena" that contains:

Code: Select all

@echo off
"C:\Program Files\Microsoft Visual Studio\2022\Community\Msbuild\Current\Bin\MSBuild.exe" -m
pause
Note: Your install location might be different. Adjust accordingly.

14.) Execute compile.bat. Wait for it to finish. Check to make sure it's error free at the end.
15.) Convert all data files to SQL so you can use MariaDB via running "\rathena\yaml2sql.bat". (you will have to confirm with "Y" ten times during this process)
16.) Open "\rathena\sql-files", delete the following:

Code: Select all

item_db.sql
item_db_equip.sql
item_db_etc.sql
item_db_usable.sql
item_db2.sql
mob_db.sql
mob_db2.sql
mob_skill_db.sql
mob_skill_db2.sql
readme.md
17.) Open "\rathena\sql-files\compatibility" and move "item_db_re_compat.sql" and "item_db2_re_compat.sql" up one level to "\rathena\sql-files". You should now have 16 files (not including folders) inside "\rathena\sql-files".
18.) Open Laragon. Click Database. Click New. (bottom left)
19.) Under "Session Name", change "Unnamed" to "Laragon". Then click "Open".
20.) Click "manage user authentication and privileges" in the top bar.
21.) Click "Add". Change username to "ragnarok". Change password to "ragnarok". Checkmark the "Global Privileges" box. Click Save. Click Close.
22.) Right click "Laragon" in the top of the left column. Expand "Create new". Click "Database". Enter name "ragnarok". Click OK.
23.) Click "ragnarok" in the left column. Go to "File" in the top left. Expand and click "Run SQL File". Direct to "\rathena\sql-files\". Select all 16 .sql files. Click Open. Confirm auto-detect. (let finish)
24.) Click "refresh" in the top bar. (next to manage user authentication and privileges)
25.) Expand the "ragnarok" database in the left column. Click "login" which will bring it up on the right. Click the "data" tab.
26.) Change the account's userid and user_pass to match the server communication username and password created back in step 3.
27.) Close these windows. Get back to having Laragon running in your system tray.
28.) Open "kRO_FullClient_20210406.zip", extract "msvcr110.dll" into "\rathena".
29.) Go to "\rathena", execute "runserver.bat". Three consoles: the login, character, and map servers are going to open.
30.) As each part comes online you'll need to grant it firewall access.

Note: We're spinning up the server to make sure we're good before moving on. You should see all green status updates.

Note: If you plan on including WAN clients, then you'll need to open the: 5121, 6121, 6900, & 80 ports on your network firewall / router. Please consider this a large security risk! The scope of this document does not include properly securing an exposed server. Proceed with caution.

12.) Click the "Load Client" button at the bottom.
13.) Click the "Load Profile" button to the right of it. Select and open the "profile.log" file just created.
14.) Some modifications require input. As each prompt appears, edit them as follows:

Code: Select all

DATA.INI
System/itemInfo_EN.lua
100
System\achievement_list_EN.lub
System/Towninfo_EN.lub
System\PetEvolutionCln_true_E.lub

Using wrong servertype in clientinfo/sclientinfo xml. Please change servertype to correct one.
Note: You'll notice how two of them don't ask for a file extension, which is why we leave it off. That is not erroneous.

15.) You should have 70 enabled patches when finished. Click "Apply Selected". Close Nemo.
16.) Clean up the "\client" directory by deleting the following no longer required files:

Code: Select all

Note: This should leave you with 58 files inside "\client". (8 folders + 50 misc)

17.) Go to "\client\data". Open "clientinfo.xml". Change it too:

Code: Select all

<?xml version="1.0" encoding="euc-kr" ?>
<clientinfo>
	<desc>Ragnarok Client Information</desc>
	<servicetype>korea</servicetype>
	<servertype>primary</servertype>
	<connection>
		<display>GoblinRO</display>
      		<address>192.168.1.130</address>
      		<port>6900</port>
      		<version>55</version>
      		<langtype>0</langtype>
   	</connection>
	<connection>
		<display>OpenKore</display>
      		<address>127.0.0.1</address>
      		<port>6901</port>
      		<version>55</version>
      		<langtype>0</langtype>
   	</connection>
</clientinfo>
Note: Inside the first <connection> block, change the <display> name and <address> to match your server. If WAN, you can use services like No-IP.

18.) Go to "\client". Execute "opensetup.exe". (decline Telemetry prompt) Change the options to match your wants and needs. (graphics device, resolution, etc)

Note: I personally like 1280x720 when playing in a window. Specifically while using X-Kore which we'll cover later.


[ The OpenKore Client: Packet Extraction, Configuration, and Field Updating ] [ Best Client ]

Note: Steps 1 and 2 are educational. Worth learning but can be skipped as I've already done this for you.

01.) Extract Winsock Packet Editor (WPE). Allow the executable if Windows Defender or your anti-virus software flags it.
02.) Using "WPE PRO - modified.exe" follow the Openkore Wiki Connectivity Guide to obtain master version and version number. (screenshot)
03.) Extract OpenKore.
04.) Go to "\openkore\tables" then open "servers.txt". Find "[Localhost]" towards the bottom. Replace with:

Code: Select all

[Localhost]
ip 192.168.1.130
port 6900
private 1
master_version 0
version 128
charBlockSize 155
serverType kRO_RagexeRE_2020_04_01b
serverEncoding Western
addTableFolders kRO/RagexeRE_2020_04_01b;translated/kRO_english;kRO
Note: Change the IP address to match your server. If WAN, you can use services like No-IP.

05.) Go to "\openkore\fields". You'll notice inside are a number of folders labelled by episode number. You're going to want to take all the files out of each of these episodic folders and move them up a directory. Overriding the ones currently in your "\openkore\fields" folder.

Note: We're doing this so that the bot can understand the map layouts of the newer content. The rAthena emulator is always improving but currently at the time of posting goes all the way to Episode 18. You might notice the bot is currently only developed up to Episode 17.1. If you play that far then you'll probably have a good idea on making the bot work in uncharted waters. For now, don't worry about it one bit. You're good for a loooooong time. Hell they'll probably have it included by the time you make it there.


[ Logging Into Your Server, Making a GM Account, and Playing! ]

Note: Even if you want to go straight to using OpenKore, we're going to use the kRO client to finish off the server and make our first accounts. While these steps can be done in OpenKore, it's easier to just follow along using a visual interface for now. If you've picked this project up at a later date, then make sure you've started the rAthena servers. (go to "\rathena", execute "runserver.bat")

Using the kRO Client:
01.) Go to "\client" and execute "2020-04-01bRagexe_patched.exe".
02.) Select "GoblinRO" when prompted. (the server name you entered previously)
03.) At the login screen type "admin_M" to make a new account on the server. You need to enter a 6+ digit password as well. (123456)

Note: The first account is always a GM account. This has a different set of sprites used that are not compatible with actually wanting to play the game. They look cool because on the off chance you actually crossed one it needed to be unique. Generally you only saw one if you were about to get banned for botting or hacking so it was quite the event to casually see an admin. LOL!

04.) Make a new character you're going to use to pwn rule breakers. Once in game, hit escape, then click "exit to windows".
05.) Open Laragon. Click Database. Click "Open" in the new window.
06.) Expand the "ragnarok" database. Click "login" again like we did in Step 25 of setting up rAthena. Click the "data" tab.
07.) Look for the newly created admin account under the server account. Change it's "group_id" to 99. (now has full GM powers)
08.) Close these windows. Go back to having Laragon running in your system tray.
09.) Once again head to "\client" and execute "2020-04-01bRagexe_patched.exe".
10.) At the login screen let's make a real account to actually play on. Once again, "yourname_M" or "yourname_F" (male or female) to make a new account on the server.

Note: The sex you select here is only used for account management and does not effect the sex of your characters you make in game. It's pretty much pointless.

11.) Spend extra time picking the right hair style, color, sex, and race. This is your new character!!
12.) Play the game!

Note: Future logins do not require the _M or _F after your account name. This is only done the first time to register a new account on the server from inside the client. You can also register accounts with the Flux Control Panel if you like. If you ever want to delete a character, it'll ask you for your email address as a security check to confirm. Accounts created in client automatically get registered with "a@a.com" as their email address in the database.

Using the OpenKore Client:
01.) Go to "\openkore\control". Open "config.txt".
02.) Line 6: add "Localhost".
03.) Line 7: add "0".
04.) Line 8: add "Goblin". (your username) (do not add _M or _F)
05.) Line 9: add "123456". (your password)
06.) Line 11: add "0". (number / position of your character)
07.) Save file.
08.) Go to "\openkore" and execute "wxstart.exe". (wait for it to process maps and finish loading)
09.) Play the game!

Note: OpenKore does not currently support the new character start maps. It'll just throw errors in the console about not being able to navigate. Use the kRO client to at least get out of the introduction area. You can walk directly through the beginning and board the ship to Izlude. It's not required to interact with anything if you don't want to. There is stuff to do though, up to you.

Using OpenKore inside kRO via X-Kore:
01.) Go to "\openkore\control". Open "config.txt".
02.) Line 23: change "0" to "3".
03.) Line 30: change "ragexe.exe" to "2020-04-01bRagexe_patched".
04.) Save file.
05.) Go to "\openkore" and execute "wxstart.exe". (wait for it to finish loading)
06.) Go to "\client" and execute "2020-04-01bRagexe_patched.exe".
07.) Select "OpenKore" when prompted.
08.) Login via your normal username and password for the account.
09.) Select your character at the next screen.
10.) Play the game with two clients at once!

Note: I highly suggest running kRO in windowed mode for ease of use. This way you can bounce back and forth between the clients effortlessly. You do not need to keep the kRO or OpenKore windows as a focused priority. You can literally open other applications on top of both without any pause to the botting. You'll hear it in the background still playing the game while you're reading the wiki, checking email, or just doing whatever you please.


[ Troubleshooting The Situation ]

Note: Having an odd problem loading software at any point? Getting an error and not sure why? I'm not sure why either so give this a whirl.

01.) Extract "Visual-C-Runtimes-All-in-One-Feb-2022.zip"
02.) Execute "install_all.bat".
03.) Wait for it to finish.
04.) ??? Try Again ???
05.) Probably Success.


[ Packaging It Up For Transportation ]

01.) Make a new folder called "GoblinRO". (or whatever you like)
02.) Place your "\laragon", "\rathena", "\client", & "\openkore" folders inside it.
03.) Make a new folder inside called "troubleshooting".
04.) Copy "Visual-C-Runtimes-All-in-One-Feb-2022.zip" into "\troubleshooting".
05.) Compress your "GoblinRO" folder. (zip/rar)

Note: Transportation or not, I suggest you make a backup like this once you're finished. Always a good idea! Also compressing it greatly helps transfer times to things like USB drives or across networks. Not only is the file size reduced from around 5.5GB to 3.9GB but the fact that it doesn't have to work with the insane amount of small files present is a life saver. Remember you can always just extract the /client or /openkore folder if you're on computers that aren't running the server.


[ Post Install House Cleaning ]

01.) Delete the Master List of downloaded files required for install. (18 files, 3.8GB)
02.) Uninstall Microsoft Visual Studio 2022 Community Edition. (7.62GB)

Note: You will lose your ability to compile the server again if you make future changes.


[ Conclusion ]

Alright! Way to make it to the end! I spent a week constructing this. Across that time, I reached out to a lot of the related discord servers and forums. Mainly making sure my instructions were correct and up to date. At most stops I was met with silence then a private message with a price tag. Anywhere from $10-100 an hour, just for their working knowledge of an old MMORPG. For truly custom work I do understand it, but for basics? It really only motivated me more to put this out.

I'd like to help remove the ridiculous paywall that has slowly started to surround this information. Sure, this has been a deep dive into an esoteric world. This game is over twenty years old at this point. Though it saddens me to see information omitted or even removed in order to sell it back to people as a service. I think that's not only harmful but gating something we have all enjoyed for decades. This is just information, there is nothing deserving of your currency. Everyone should be able to do this, for free.

I hope you have found this both helpful and educational! Feel free to translate into your local language and distribute. I have done three trial runs across different machines and have not had a problem. If you're experiencing issues check that you haven't missed a step. Need support? Check the forum, wiki, github, and discord for both rAthena and OpenKore. Still can't find a solution? Post here! I cannot guarantee a timely response but I will check back in occasionally and try to help out as much as I can. Thanks for reading! /cheers
Although I do not know you, I am sure that you are a very enthusiastic, enthusiastic and kind person. Your article is very detailed. Bed like you put a lot of your time in it. Wishing you a lot of health and good luck in life.

Re: Creating an Open-source Ragnarok Online Server with kRO & OpenKore Support

#4 Post by nnbite »

hello whitegoblin
Sorry for my language I use google to help translate.

Thank you for your effort.
Now I've tried following the steps but I don't know why there's a problem installing laragon, creating the compile.bat file and the files aren't complete as you suggested. It may be because the versions of various tools have been updated a lot.
So I would like to ask you to help me pack everything that has been configured like anaqonda newbie pack for me. (I tried connecting OPK to anaqonda's server, but I failed) Thank you.
