I tried to insert my custom weapon icon into the game. The graphics offset is C5EA4. Before that, I already inserted custom animation and everything worked just fine. But everytime I inserted icon using GBA graphics editor, animation either glitches or won't play at all. FEditor spell animation manager won't open again as well. Finally I tried to delete nlz file and sav file and retried, but it still screwed up...
I don't know what to do now. :( Can someone help me?
To make it more detailed, I used the full icon sheet extracted from the rom.
