Byte 808000 Debug#

The byte at SNES address $808000 is a bit field of debug flags. It's set to $00 to turn all the functions off. Use Pro Action Replay (PAR) code 808000xx where xx is the bit(s) for the debug features to turn back on.

This needs some investigation.

Sound Test#

The access method and appearance of the sound test is almost identical to the one seen in Super Hanafuda 2. The programming located at SNES address $80802F-808049 used to reach the sound test is always branched over. Use Pro Action Replay (PAR) code 80802E00 or Game Genie code DD64-476D to change this behavior. Then, hold X button during bootup to open the sound test screen.
