I was trying to hack attack that only apply to monster's attack but it does not work. first hack attempt, mosters and enemies get very low attack like 10. 4th hack attempt, i keep getting game data error before i attack an enemy.
If you have ARM knowlegde, do you know where to modify so only monsters have high attack? if you want to test it, search offset 16FDF8 and try modify #0x ??? to #0x FF, #0x FFF or #0x FFFF
