FIFA 97 (Game Boy)

Why did they disable palette and controller settings again? Also another sports game... that has a Super Game Boy soundtrack. Yay!

Unused Super Game Boy Functions
Tiertex may have planned extra Super Game Boy features and may have cut back on a few likely due to time constraints, or other reasons.

SOUND
A single packet can be found in the listing located at  and is never called. SOUND calls  SPC700 ports allowing Game Boy games to use the internal Super Game Boy sound effects and even more rarely, music or custom small sampling areas loaded into the Super Game Boy via SOU_TRN command, and in some cases, the JUMP command as seen in Nekketsu! Beach Volley dayo Kunio-kun. Games that use Super Game Boy internal sound effects include Kirby's Dream Land 2, The Pagemaster (Game Boy) and others. Games that contain Super Game Boy soundtracks include Donkey Kong (Game Boy), Animaniacs (Game Boy), Hercules, Small Soldiers, A Bug's Life, Pro Mahjong Kiwame GB, and others.

PAL_PRI
PAL_PRI. Super Game Boy packet, when bit is set to , palettes are switched back to default when directed to by the game, and since palettes are disabled by the game, this is unnecessary and leftover from a probable early idea to merely have them switch back instead of disabling them as seen in Kirby's Dream Land 2, Donkey Kong (Game Boy), Donkey Kong Land and others. Loaded after PAL_SET with all bits set to and referenced twice in the game's packet ordering. Since palette settings are disabled by the game, the function is useless and unused either way. Game Genie codes will enable palette and control settings while setting the PAL_PRI bit to.

JUMP
Used to set the SNES Prgram Counter to a specified address. Alternatively, the JUMP can be used to set a new address for the SNES NMI handler, the NMI handler remains unchanged if all bytes 4-6 are zero. shows a JUMP Super Game Boy Packet that is loaded during startup though it is never called and doesn't have any function. Unlike Olympic Summer Games (Game Boy), the JUMP is never actually loaded. Examples of JUMP can be seen in Nekketsu! Beach Volley dayo Kunio-kun and GB Memory.
