Unused Super Game Boy Commands

beatmania GB is one of the many games that contains a completely-unused set of Super Game Boy commands that are likely remnants of a Nintendo tech demo or devkit given to developers to see the many available enhancements in action. Starting at 0x91FF is the full listing. This time, the listing diverts slightly in packets and for some reason it becomes moved out of sync. It appears to have been spliced some time during development for unknown reasons. Could have been used for testing what impressive features Konami wasn't going to use.
