I tried RO Tools and Packet Extractor on Ragexe.exe (task manager showed it when game was running, so it was not launcher) and both of them ended up with error:
=================[ ERROR ]==================
Sorry I cant find the offset of the packet length function.
The executable file might be compressed/protected.
