The game crashes on various points in-game. Getting to these points in no$gba shows warning about undefined opcode:

Attached savestate from no$gba debug version. Get to the boss and watch the warning kick in after a few seconds. Same place triggers it in GBARunner3.

In GBARunner3 you can use the password 4RC8! and enter challenge mode to test this.

I've tested this with the latest commit bb9c06b + manual JIT patches and the described issue is still happening.

This also happened on mGBA at some point, it seems that this game has an AP measure that checks for existing save-data functions/files, which shouldn't be on a real game since it uses a Password system instead.

Adding a save override option for this game to not save could fix it.
