version 1.0.2 still doesnt work

Downloading the exe now. It seems like there was a single kRO exe that uses something bizarre, or someone creating private server exes tampered with something. You both have the same entry point and code size.

Edit: Ok, fixed it. As an added bonus I'll attach the recvpackets.txt from the exe for the lazy.

JCV's RO Tools 1.0.3

Functionality
1.0.3 works with all official ragnarok executables that are not packed. It should also work with almost all private server executables, although there is a chance the server provider has packed the exe. If you have an exe that does not work with this release, please post it.

I reccomend uploading this to the main openkore site and linking to it in the wiki in place of the openkore packet extractor. JCV's tool and the official tool work in a very similar way, but JCV's tool is much easier to maintain. The down side to JCV's tool is it has undesirable and outdated options in addition to the packet extractor.

Changes
-Changed how the packet length function's end is found
-Cleaned up output messages
-Added addresses to appropriate messages
-Stopped packet length output to console

Technical Explanation
There is no NOP after the packet list building function in that executable. JCV's packet extractor looked for a "NOP" to signify the end of a function. Searching for "RETN" finds no function end because the disasm used doesn't interpret certain lines. I made it find "POP EBP" and it works out fine for the packet length function. The old version would find the packet list "end" at the end of another function,and then recurse backward to the wrong function start.

1.0.3 just worked perfectly and after updating the server datas using the server info finder everything just works (well i get alot unkown # in towns but aslong as it just works )

just say.... ITS ALIVE !

thx alot to everyone who helped *looking for karma button* well dont looks like i can do anyhting other then saying a big "THANK YOU GUYS"


(just in case someone has the same error as me after updateing the recvpackets.txt

to all thse who just updated their recvpackets.txt and still getting alot of unkown # just follow this guide http://forums.openkore.com/viewtopic.php?p=10570#p10570

If 016C is not in recvpackets.txt manually add it as length 43, or else you will receive random disconnects

I haven't checked if JCV's properly checks for that type, but I highly doubt it because it is the first packet that looks like that in the length function. Putting how to fix it here for now, will actually fix it later. It's the same as others, but the packet id is identified differently

BE 6C 01 00 00

It will look like this in most disassemblers:
mov esi, 0x16C

Or like this in the one JCV uses (I think):
mov esi, 16C

JCV's RO tool seems to have a problem...
I am playing pRO specifically valkyrie server...
i download rotools_103.zip w/c Motivus posted lately...
i extracted valkyrie.exe and all i got was this

==================[ ERROR ]==================
Sorry I cant find the offset of the packet length function.
The executable file might be compressed/protected.
=============================================

my question is how to solve this problem...
do the tool supports pRO also?

[gex00]

Do you guys have any updated version of JCV ro tools if you would you mind uploading it cause I tried all the best ways I could do to solve the Unknown Packet when botting in forsaken RO but nothin seem to work....

Any help would be appreciated.

sry for the bump

[moronish]

all the links for the packet extractor are dead. Could anybody re up the links?Thanks a bunch.

[Infinite Sphere]

Would someone consider posting a working link again? All the links in this thread are dead.
