At least 3 monster battle with same monter. Go to field to fight monster. After fight u will gain exp. Search that exp on dword. Example 2150. There are plenty of result between 80 to 190. Choose starting from B and C address and change increase value by 1. Fight next monster to find which address has changed. If found, change value to 999999. Fight next to get level up.
after several tries, sometimes works sometimes force close when change value exp to 999999
the problem are even after change increase value by 1, there are still 50+ address. So how to know which one exp value?
