Yu-Gi-Oh!: Monster Capsule

Cards and monsters. Maybe a capsule.

Sound Test


Game Genie code or Gameshark code  will start the game in a sound test.

Unused Palettes
Game Genie code will replace the main palette with one of three unused palettes. The main palette is also loaded before the Konami logo, so an additional screen may have been planned. The third palette is a slightly greener version of the second.

ICON_EN
Palettes were likely going to be disabled at some point early on during development. Game Genie code will set ICON_EN to.

DATA_SND
Aside from the standard INIT DATA_SND packets, there are additional unused ones which might suggest that a Super Game Boy soundtrack or custom samples were planned at some point during development. The entire listing is loaded during startup and is located at. There is also a SOUND command right before the ret  instruction appearing before the commands. 795D08000B8CD0F46000000000000000 795208000BA9E79F01C07EE8E8E8E8E0 794708000BC4D016A5CBC905D010A228 793C08000BF012A5C9C9C8D01CA5CAC9 793108000B0CA5CAC97ED006A5CBC97E 792608000B39CD480CD034A5C9C980D0 791B08000BEAEAEAEAEAA901CD4F0CD0 791008000B4C2008EAEAEAEAEA60EAEA 790009000BADC202C909D01AA9018D00 790B09000B42AFDBFF00F0052073C580 791609000B032076C5A9318D00426868 79210900016000000000000000000000 79000800034C00090000000000000000
