SOUND TEST
Bomber Man Max J GBC Sound Test.png
A sound test exists in all versions of the game. Press Right, Left, Right, Right, Left, Left, Right, Left, Right, Left, Left, Right at the main menu, then choose any option to access it. Alternately, Game Genie code 0F8-8BD-E6E will replace the introduction sequence with the sound test in Blue Champion and Yami no Senshi, 0F8-99D-E6E for Red Challenger, and 0F9-23D-E6E achieves the same effect in the Hikari no Yuusha version. Lastly, Game Genie code 0F8-B4D-E6E will set the introduction to the sound test in the Japanese exclusive Ain Version of the game.
Unused SGB Palettes
Oddly the Ain Version will load the Hudson logo before transitioning to the black GBC-only message and will display the single used system palette 01 setting which is located away from the main list at 0x3BA7. This might suggest that the single palette was added very early on when support for the Super Game Boy was ceased.
An entire PAL_SET listing also exists. Only the palette located at 0x159E0 is used and is loaded during startup. The entire listing starts at 0x159E0. Apparently this list was drafted later during development as the listing was not finished and there is space offering room for eight additional palette settings. Game Genie code ?0B-AAC-E61 + 5?B-ABC-086 (?0-F0, 59-5A) will load the selected default palette.
Probably going to look at the rest of the Bomberman GB games next week.
