This page contains notes for the game Mario's Picross.

Loose information about the Super Game Boy SOUND function loaded during startup. While this doesn't explain much, it is enough to invite a small amount of curiosity. It is unknown why this was programmed since Super Game Boy sounds are not used anywhere. Maybe this was an early idea for a song or a Nintendo jingle was intended to play here? Probably not going to finish.
