SquareBoi is the DIY Game Boy Cart You’ve Always Wanted

Running unofficial code on a Nintendo Game Boy has long been a solved problem. However, you still need a way to get that code onto the handheld console. The Squareboi cartridge promises to do just that, as created by [ALXCO-Hardware].

It’s a well-featured cartridge, with up to 4 MB of ROM storage onboard. It also features a ferromagnetic RAM part for savegame storage, which doesn’t need a battery to hang on to your precious data. It’s designed to be compatible with the vast majority of Game Boy and Game Boy Color games, with efforts made to support the most common mapping schemes. It can be built using entirely through-hole components, and is readily programmable via an Arduino.

For those eager to tinker with code on the Game Boy, diving into the Squareboi is a great way to get closer to the bare metal and understand what’s really going on at the low level. Those interested in building their own can get all the relevant details over on Github.

We’ve seen similar hacks before, too, like the cartridge that brought Wikipedia to the humble Nintendo handheld. If you’ve been whipping up your own Nintendo hacks, be sure to drop us a line!
