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.
SmallBASIC is a free interpreter for BASIC, a simple computer language, targeting simplicity, mathematics, and graphics. Also, it has a powerfull string library, supports external C modules (shared libs), uses dynamic arrays (by default) and has no data types.

Plasma EBG is an empire building game with an isometric view. It runs in multiple resolutions with graphics being displayed better for higher resolutions; hence, lower resolutions do not suffer from being too large, etc. In the future several viewing engines will be available, such as EBG-opengl and EBG-2d. There is a separate module called EBG-dev which features the latest AI-development, as well as a separate server module.
AA-lib is a low level gfx library just as many other libraries are. The main difference is that AA-lib does not require graphics device. In fact, there is no graphical output possible. AA-lib replaces those old-fashioned output methods with a powerful ASCII art renderer. The API is designed to be similar to other graphics libraries.
