Game Boy Enhanced (GBE for short) aims to be a fully functional Game Boy emulator. The goal is to create a highly portable emulator using C++ and SDL 1.2, document the Game Boy's functions through clear code, and add as many enhancements (scaling filters, cheats, custom sprites) as reasonably possible.
