CwCheat Support

[LunaMoo]

@Adamloh1997 one or more of the cheats you used is probably just crashing the game, disable cheats and it should boot fine.
By your description the crash is instant after booting, so if you created a custom game settings for it, remember you can enter game settings by pressing and holding game icon for a few seconds. You could also go to memstick\PSP\Cheats and remove the cheats manually, they're stored in *.ini files named by game ID.

Instant crash is probably safest thing you can get from broken cheats, smaller issues can easily corrupt your savedata or cause other game breaking issues over time.
