Ok first of all you download the right hack ( german/english )
if youre playing english one you probably need the bypass posted in shaiya section.
After you replaced the bypassed game.exe with your original one you start up shaiya. There shouldnt be any update coming up if youre starting it by game.exe.
Now you just go ingame, open the hack and click the hacks. Or you use the hotkeys.
If i got time il make a trainer in vb or something.. so you can chose hotkeys and all. Tho its taking alot of time wich i dont got atm .. so yea please be patient
i hope it helped you
