gnuboy emulates the Color GameBoy handheld console
in portable C, with interfaces for X11, Linux
fbcon and svgalib, SDL, DOS, and Windows, with
other ports planned in the future. Compatibility
with ROMs tested is around 99 percent, and all
major hardware features except SGB extensions are
supported. With the optional optimized i386
assembly code, gnuboy can run at the full 60 FPS
even on Pentium/75s and below. No special
libraries are required to compile, and gnuboy is
known to build on many *nix variants.
