Undo game.exe changes?

Hey guys,
I used the Shaiya Patcher to change my game.exe.
How can i reverse them,
What are the codes in client to edit:
multiclient;
Disable updater;
Wallhack;
Anti-Freeze.

I'd like to have those so i can manually edit my client,
to reverse the stuff Shaiya Patcher has done.
Hope you guys can help

Use another game.exe :P

If you don't have the back-up of it, the best/faster way will be by getting a new one

Look at the Source Code from Shaiya Patcher the Hex codes in it use brain.exe

Yeah i figured i'd need to use a new one. Thx for the responses.
