Never told you that I love you? :D

I downloaded it but it keep saying
==================[ ERROR ]==================
Sorry I cant find the offset of the packet length function.
The executable file might be compressed/protected.
=============================================
I think u got the wrong file, you got http://www.snapdrive.net/files/46209/RO%20tool.rar but the one that is modified is http://www.snapdrive.net/files/46209/Ro%20Tools.rar (164kb vs 1.5mb) that actually has password, try it if you have some time.

Thxs a lot kLabMouse.

Simple. Just reverse engineer absolutely everything in the exe, or do the same with the compression method (I think most are one-way, so good luck with that).

Seams so easy when you say it, but I don't know a thing about reverse engineer :) Is really that hard?

I couldn't get the new packet extractor to compile, and I think returning to the old method with the perl file and a dump exe isn't needed. I posted how to fix it in the first post. If anyone is interested in doing so, go ahead. It's a very simple change.

For the time being rocha can dump recvpackets.txt from any running exe, including those protected with gameguard. I also might post something in the near future if no one has any interest in fixing it.

Thxs sli.
I was being a sarcastic bastard. :lol: All of that would be ridiculously hard. You're better off trying to dump everything from a running EXE like Motivus said.

I'm surprised. It was easy to compile. Here's the modified version (supports both old and new style clients) and source.

i just tried the JVC's RO Tool v1.0.1 but it didnt work either

Code: Select all

Sorry I cant find the offset of the packet length function.
The executable file might be compressed/protected.
i tried on when the exe was running and with the "fin storage key" tick

am i to stupid to use it? or is my exe maybe protected different (just uplaoded it to RS)

Exactly! JVC's extractor isn't working either. The exe has a completely new pattern.. Please can't anyone have a look at this?? :O

Does your compiled version work on every .exe? including the new ones?
i havent checked yet
