Debug Menu#
Enabling the below code will change the Voice Setting menu to this debug menu. Nothing too interesting can be done here since there appears to be no code in the game to actually switch this debug menu to the PlayStation 2 version. This is all hard-coded to PlayStation Portable settings.
The options in order are a controller configuration screen that will change actions assigned to a button, second plays some music, third allows you to save or load with the PSP save screen, finally, the last option would switch between PSP and PS2 settings.
