Homebrew overview
Homebrew Overview
Homebrew refers to software written by hobbyists and independent developers for hardware long after its commercial life ended. The Game Boy has a thriving homebrew scene because its hardware is simple, thoroughly documented, and easy to develop for with free modern tools. From full games to music trackers and utilities, homebrew breathes new life into the DMG, Pocket, and Color.
What counts as homebrew
- Original games built from scratch and distributed as ROM files or physical cartridges.
- Applications such as music trackers, drawing tools, and clocks.
- Demos that push the hardware to show off graphical or audio tricks.
Most homebrew is written in C using the GBDK toolkit or in assembly with RGBDS. The result is a ROM file that runs on real hardware through a flash cartridge or on an emulator. Because the Game Boy is so well understood, the barrier to writing your first program is low, and the community shares plenty of open-source examples.
Legal note
Homebrew is legal because it is original work made for hardware you own. This is entirely separate from downloading commercial ROMs, which is copyright infringement. Stick to homebrew and your own legally created backups.
How to run it
To play homebrew on a real console you need a flash cartridge, a way to copy ROMs onto it, and the homebrew files themselves. See the running-homebrew page for the practical steps. homebrew
