GnuBoy SVN r197 is released. GnuBoy(all lowercase, but sometimes unofficially spelled GNU Boy) is a Free Software emulator released under the terms of the GNU General Public License ("GPL"). It is 99% execution-compatible with software targeted for the Game Boy ("DMG") and Game Boy Color ("CGB") handheld game consoles sold by Nintendo. It is not compatible with Super Game Boy-specific features or with Game Boy Advance, though it can run Super Game Boy games in DMG or CGB mode.
