Cheats crashing game in mobile

[LunaMoo]

There was some change to delay slots behaviour to match real PSP I believe, but don't remember details. That's one thing which could have affected assembly cheats.

Edit: Actually my brain wasn't quite open when I thought about this answer, my assumption of assembly cheats is towards something which hooks to existing functions that patches game behaviour and values in registers, however one could also create "assembly cheat" that patches game memory via some static address and that might easily change between emulator updates resulting in a crash, can't really tell what's the case without seeing the crashing cheat.
