Pokemon LeafGreen GameShark Codes

LeafGreen shares its underlying engine with FireRed, but its GameShark codes aren't always identical — memory offsets can shift slightly between the two ROMs, so codes should be matched to LeafGreen specifically rather than assumed interchangeable. The list here has been checked against the standard USA v1.1 LeafGreen build.

These codes cover the same core needs as any Gen III cheat list: guaranteed legendary catches with infinite Master Balls, fast leveling through Rare Candy generation, and options for grabbing wild trainer Pokemon or triggering a shiny encounter without the usual odds. Every code below has been tested and confirmed working on Delta Emulator.

Use these selectively — leave Rare Candy and the encounter modifier off if you're going for a save you'd want to call legitimately earned, like a completion or shiny-box save others might download later.
