 Gameboy Color, Gameboy Advance), Sega (Master System, Game Gear),
 NEC (PC Engine, SuperGrafx) and Bandai (WonderSwan, WonderSwan Color).
 It was formerly called bsnes and the SNES emulation is especially
 complete and polished.
 .
 higan strives to provide the most faithful hardware emulation possible.
 It focuses on accuracy and clean code, rather than speed and special
 features. It is meant as a reference emulator to document how the underlying
 hardware works. As a result the minimum system requirements are high.
