SUPER SOUND TEST

Planned Super Game Boy Soundtrack
Located at is a single SOU_TRN packet suggesting that a Super Game Boy was planned sometime during development. Song table starts at showing five songs as well as a song mute command. Pac-Attack has more than five songs, so this table could refer to anything.

Planned Super Game Boy Sounds
Located at is an entire SOUND packet table suggesting that internal Super Game Boy effects were planned sometime during development. Wario Land II (Game Boy) and Pro Mahjong Kiwame GB also feature a full Super Game Boy sound table which appears to be remnants of a Super Game Boy dev-kit, so maybe this table is leftover from an early testing stage.
