RGBDS (Rednex Game Boy Development System) is a free assembler/linker package for the Game Boy and Game Boy Color. It consists of: * rgbasm (an assembler) * rgblink (a linker) * rgbfix (a checksum/header fixer) * rgbgfx (a PNG-to-Game Boy graphics converter) This is a fork of the original RGBDS which aims to make the programs more like other UNIX tools.
