Debug Flags

Bit 01 - Disable Collision

Use Pro Action Replay (PAR) code 80853500 or Game Genie code DD67-1F0F to enable a debug flag that allows one to disable collision by pressing Select on controller 2 during gameplay. It also toggles bit 01 in 7E00FB.

Bit 02 - Reset

Use Pro Action Replay (PAR) code 848F3500 or Game Genie code DD67-3F97 to enable a debug flag that allows one to reset the game by pressing Start+Select simultaneously.

Bit 04 - Reset

Use Pro Action Replay (PAR) code 80840B00 or Game Genie code DD6D-44AF to enable a debug flag that when starting a stage, it'll jump to $A08000 which will reset the game.

Bit 08 - Unknown

This needs some investigation. Discuss ideas and findings on the talk page.

Use Pro Action Replay (PAR) code 80FB9C00 or Game Genie code DDEB-37D4 to enable an unknown debug flag where pressing Select jumps to $A082D9 and pressing Start checks to see if the value on the stack is zero.

It's currently unknown how to reach the code where this flag is checked.

This bit is not checked.

Bit 20 - Clear Stage
