Useful Cheats#

Revised Moonjump (Hold L)#

The moonjump cheat that most people know has the side effect of stopping the player's horizontal movement if they crash into a wall or if they start a moonjump from stand still.

This version of the cheat fixes those issues, and allows the player to always be able to keep moving horizontally while levitating. This version forces the player to be in the "jumping" state (so that the player can always move while in the air), plus it forces the game to execute the functions that calculate jumping movement while doing the moonjump (this prevents an issue where, if you were sliding and then started a moonjump, you wouldn't be able to move horizontally).

Camera does not collide / get stuck in walls#

Avoids the camera getting stuck in walls under certain circumstances.

Hold R to go through collision#

No Actors#

Prevents map entities from appearing.

Warp to Map / Entrance / Cutscene#

While in-game, press the GS button to warp to the specific map, entrance and cutscene you want.

• XX = Map
• YY = Entrance
• ZZ = Cutscene (00 = No Cutscene)

No Fall Damage / Fall Death#

Removes fall damage / fall death. Useful to use alongside the moonjump code.

No Save Checksum Verification#

Disables save file checksum verification. This allows the user to edit the save game without having to recalculate the checksum.

No Fog#
