The Game Boy Is Still Alive: Homebrew on the DMG-01
Most consoles die when the shops stop stocking them. The Game Boy never quite got the message. Decades after the last official cartridge shipped, a thriving community of developers is still writing brand-new games for the 1989 hardware, pressing them onto real cartridges and selling them to players who want something fresh for their DMG-01. This living homebrew scene is one of the most exciting corners of the modern hobby, and the collection deliberately documents it, because a museum of the Game Boy should preserve its future as well as its past.
Here is a tour of the Game Boy's second life, from the new commercial cartridges on the shelf to the tools that make them possible, and a game we built ourselves.
The New Cartridges
The clearest proof that the platform lives is a shelf of games that did not exist when the console was new. The collection holds Deadeus, an atmospheric horror game distributed by Incube8 Games in which a dream warns that the whole town will die in three days, and it is every bit as unsettling on a green screen as that sounds. Beside it sits Shapeshifter II from Greenboy Games, part of a wave of modern boutique publishers producing polished, properly boxed cartridges for original hardware. These are not emulated curiosities; they are real Game Boy games you can slot into a real Game Boy, made by people who chose the constraints of 1989 on purpose.

The Tools That Made Them Possible
Modern homebrew rests on decades of community effort to understand and re-tool the hardware. Developers today write Game Boy games in C using long-established development kits, or assemble them visually in accessible tools that hide the assembly language behind a friendly interface. Either way, the workflow ends in the same place it did in 1989: a small ROM image that behaves exactly like an original cartridge. What has changed is that the knowledge, once locked inside Nintendo and a handful of studios, is now open to anyone with a laptop and some patience.
Getting Homebrew Onto Real Hardware
A ROM on a computer is one thing; playing it on the genuine article is another, and that takes two kinds of hardware, both in the collection. First come the reusable flash cartridges, the EverDrive GB X7 and the earlier GB EverDrive, which carry a memory card so you can load many game files at once and run them on a real DMG-01. Then there is the piece that gets a game onto a cartridge in the first place: the Flash Boy, a writer that connects to a PC and burns your ROM onto a flashable cartridge. Between the writer and the flash carts, any game file you build can end up running on original hardware exactly as a commercial cartridge would, which is the essential bridge between the modern workflow and the vintage machine.

A Game of Our Own: Snake
We did not just collect other people's homebrew, we made one (well, at least a very basic one). Across a hands-on series on this very Journal, we wrote a complete game of Snake for the Game Boy from scratch in C, set up the tools, learned how the console draws with tiles and sprites, handled the joypad, added food and growth and a game-over screen, and finally ran the finished game on a real DMG-01 via a flash cartridge. If you want to see exactly how a Game Boy game is built, start at the beginning of the Build Your Own Game Boy Game series, which walks through the whole project one step at a time. It is the best possible companion to the cartridges above, because it shows what actually goes on inside them.
Why Homebrew Belongs in a DMG-01 Collection
It would be easy to argue that a Game Boy collection should stop at the last official release, but that would miss something important. The homebrew scene proves that the DMG-01 is not a dead artefact but a living platform, still capable of hosting genuinely new ideas thirty-odd years on. Collecting the modern cartridges alongside the vintage ones tells a fuller and more hopeful story: not just what the Game Boy was, but what it still is.
There is a practical collecting angle too. Boutique homebrew is often produced in small, numbered runs that sell out and never return, which means today's affordable new release can become tomorrow's genuine rarity. Documenting the scene as it happens, rather than trying to catch up later, is one of the quiet advantages of a collection that pays attention to the present.
