Debug Menu#
Using Game Genie codes INUKXYPO KVUKUNOV will bring up this screen. Pressing Left and Right changes the value selected (between 0x00 and 0x0D). Pressing B plays a music track, Start plays music, and Select + Start goes to a level (though any value above 0x03 will load garbage data if the player tries to go to that level).
