# FireRedLeafGreenRecomp: recompiling Pokémon FireRed and LeafGreen for PC

> This statically recompiles Pokémon FireRed and Pokémon LeafGreen, USA version 1.0, to native PC with gbarecomp. FireRed SHA-1 is 41cb23d8dccc8ebd7c649cd8fbb58eeace6e2fdc. LeafGreen SHA-1 is 574fa542ffebb14be69902d1d36f1ec0a4afd71e. The README says both games boot through the BIOS intro into gameplay. Code the static recompiler has not covered runs in an interpreter the first time, then is JIT-compiled and remembered.
