RGBDS

A free assembler/linker package for the Game Boy and Game Boy Color

Get the most out of the Game Boy hardware

Gain complete control over the console; with no middle-man, debugging is made simpler.
Push the Game Boy's limited capabilities to the limits writing native assembly code.

Complete toolchain

RGBDS' four programs cover the whole compilation pipeline into a ready-to-play ROM, from RGBGFX (the image converter) to RGBFIX (the header "fixer").
Each tool can easily be swapped for a custom one, or used stand-alone as part of another process.

Open Source

With a long history dating back to 1997, RGBDS is an open source project supporting a large community of homebrew developers. Join us to get involved, showcase your project, or get help.
The extensive documentation also allows easy integration into any workflow.
