Since the CryptDecrypt Hook method of bypassing GGCRC is patched, Is there any other way besides driver programming?

Make a copy of any code regions and load up a copy of it. Make all calls and far jumps of the copied memory go to their new positions in the copied memory. detour execution to your copied memory.

How about that?

change any code that's called before gg loads to jmp to the correct place in the copied memory then change it back before there's a check.

emulate the connection between maplestory and gameguard, then kill gg?

hes talking about copy/pasting the bytes that get loaded for the GG into your hack and calling it back to maplestory and using it as a packethack not a detection tool making it inactive.. but thats a shitload of work from the way i see it and no guarantees it will work next update.

Actually, it shoulnd't be that hard. open up ms, attach with olly and use ollyscript.

About the CryptDecrypt method: since what rev was it patched? I'm trying to create a ggcrc bypass for Flyff, which currently has gg rev 1209.
If it should work for that rev, I need to hook CryptDecrypt in GameMon.des (not in advapi32 but in GameMon's copy of it) and then just change GAMECRC=2 to GAMECRC=0 right?
