# RubySapphireRecomp: statically recompiling Pokémon Ruby and Sapphire

> RubySapphireRecomp statically translates Pokémon Ruby and Sapphire USA revision 1 ROMs into native C. Ruby SHA-1 is 610b96a9c9a7d03d2bafb655e7560ccff1a6d894. Sapphire SHA-1 is 4722efb8cd45772ca32555b98fd3b9719f8e60a9. The runtime refuses an unrecognized ROM. The files are variants/ruby/roms/ruby_usa.gba and variants/sapphire/roms/sapphire_usa.gba. gba_recompile writes the generated C, and cmake --build build --target RubyRecomp builds one executable.
