Not sure....sometimes is fairly simple and other times it's not. For this game, I believe the Money AOB is what mainly changed between updates. You can try searching for AoB of this A1 ?? ?? ?? ?? 8B 80 E4 95 59 00 C3 and update it accordingly. You have to remember to update the ASM code also that is putting the address of the money into a register.
The basic premise though is to ?? some bytes and see if you find something similar. It depends on how much code changed as to whether it works or not.
