Pro Mahjong Kiwame GB

Sigh... another mahjong game :( How many do people really need? Although this specific mahjong game doesn't suck and has a few interesting oddities... it has a Super Game Boy soundtrack and a well... one hidden from another game also exists.

Unused Mogura de Pon Music
The entire Mogura de Pon soundtrack exists in this game! Using the Game Genie code you can play them at the title Screen. Songs were not taken directly as there are noticeable differences between the two soundtracks; instruments are now monaural panned and the differences are comparable to Super Mario Land 1.0 and 1.1 soundtrack revisions. Game Boy Game Genie code is required if you are playing Pro Mahjong Kiwame GB using a Super Game Boy adapter, otherwise the enhanced soundtrack will play instead. Also note that the border will not appear when using the code.

Interestingly enough, the Pro Mahjong Kiwame GB Super Game Boy song table has enough entries for a Super Game Boy version of all Mogura de Pon songs. Song listing for the Super Game songs starts at.

Unused Super Game Boy Sound effects
Starting at is a listing of both A-TYPE and B-TYPE Super Game Boy internal sound effects. Only one internal sound effect is played when you attempt to play a VS game and is referenced away from the list as a separate entry at as. Game Genie codes will play any unused Super Game Boy sound upon selecting VS game.

Wario Land II (Game Boy) as well as a few other games share a nearly identical unused SOUND command listing. Athena likely forgot to remove the leftover code from a Super Game Boy dev-kit.
