I just located "BOOT.MP3" @ /devhdd0:/game/BLES80608/USRDIR/sys and "SOUND.BIN" is the BG music supplied in mM @ /devhdd0:/game/BLES80608/USRDIR/ Going to check it out now EDIT: afaik you can rename an MP3 to SOUND.BIN or BOOT.BIN and it will work I'm making mine super camp with this instead of the startup sound: http://themushroomkingdom.net/sounds...io_yoo-hoo.wav
