How to Use/Restart Action Replay on Game Boy SP

The Action Replay cartridge doesn't "restart" independently—it's a pass-through device that sits between the Game Boy SP and the game cartridge.

Standard Usage Steps

1. Insert Action Replay cartridge into Game Boy SP slot.
2. Insert game cartridge into Action Replay.
3. Power on the Game Boy SP.
4. Access the Action Replay menu (usually Start + Select).
5. Navigate with D-pad/buttons to select cheats, save management, etc.

To reset game progress, use the game's own options (restart, new game, reset)—not the Action Replay.
