Martial Empires XTrap info

Hi,
i need some infos about XTrap.
i tried to bypass xtrap, so it wont get loaded at the start of the game.
(simply suspend XTrap didn't help)
but i couldn't find any place in the code where there is a reference to XTrap.
also i dont know exactly where to look.
is it in the Launcher.exe or in the game.exe.

i think XTrap gets loaded by the launcer, but im not certain.
i noped a loadlibrary call -> XTrap error. (i thought im on the right way)
i noped the call a few calls earlier -> no XTrap error (but it still gets loaded)
i guess this was the XTrap update function. because after this the update function didn't pop up.

i also noticed before the first run there is no XTrap in the directory.
So my next step is to emulate the launcher (not the update, but the welcome packet) and start the game with my emulator.
if xtrap gets loaded by the launcer i should have bypassed it. if not

so i hope this will make it.

but im still glad about any hints you can give me.
because this would only be a work around.

PS: i really only need hints.
i can do it alone, i know how to handle olly and stuff.
if i can attach olly, i can contribute other stuff

Completely agree, but it would work only if you know bugs and have hacks which can be implemented via dll injection etc. But for game analyzing (finding bugs etc) removing protection is a good way... certainly, it's also possible to use Ollydbg simultaneously with xTrap

Quoting Dwar, here is some nice information

Start tracing code from beginning (game.exe). There are several functions which call xTrap (load it).

Don't touch the launcher, 'coz it useless for bypassing. All what you need are in game.exe

Yeah, if xCrap folder has been deleted and you run app from launcher, then xCrap download all modules by calling update functions from XPvaXX.dll

For Martial Empires xRat

can be disabled by 3 nop and 1 ret. Catch all termination routines and bypass them. But without emulation heartbeat packets, client will kick you in 5 sec

could you help us with the heartbeat packets Dwar?

We working together on a Bot, but without a bypass for Xtrap we cannot send any key's to the game.

I don't know how to handle heartbeat packets :/
