Nintendo - GameBoy Emulators

Name	Description
Boycott	Nifty newer Gameboy emulator with many of the same features as VGB and it supports neat backgroud skins.
cingb	This is a open source Gameboy emulator for Linux. Some games run on it.
GBE	New open-sourced Gameboy emulator. Haven't tried this one yet...
gbpablog	gbpablog is a recent Game Boy emulator written in C++, using WxWidgets and SDL. It doesn't seem to support GBC emulator, but does have sound and savestate support, and can play commercial games. Source code is only available via a Mercurial repository at the official site.
Gngb	Gngb is a GBC emulator for Linux written in C using the SDL.
gnuboy	gnuboy supports DMG, CGB and most MBCs, and has 99%+ compatibility. It still has yet to emulate the link cable, Super Gameboy extensions and obscure mappers (HuC1, HuC3, etc). Definitely worth the download.
GooBer	GooBer is a Gameboy emulator written in ANSI C with the Allegro game programming library.
KiGB	This is the Linux version of Ricky Liu's excellent GB/GBC/SGB emulator from Windows.
VenGaboyTK	A GTK port of Boycott, only Linux port available.
VGB	VGB (Virtual GameBoy) is the only GB emulator available for FreeBSD, Solaris, and SunOS as far as I know, it also is available for Linux too... It has good compatiblity, and good sound. This emulator is worth the download.
zBoy	zBoy is a pretty new Game Boy emulator created as a project by the author to learn about microprocessor architecture, assembly language, and so on. It's available for Windows, Linux, and (somewhat unusually for 2011) DOS. The source code is also available. Despite being as new as it is, zBoy seems to be able to play several games quite well, though all the site's screenshots are of classic GB games, so I don't think it does GBC emulation (at least not yet).
