Modding an OG gameboy to house a Raspberry Pi Zero (or CM3) has been a thing for a while. Unfortunately it's always been a pricey proposition, requires more than a little electronic and physical modification, and the quality of the finished product can vary wildly depending on your skill level. Now Retroflag (a company known for making some of the nicer mini-console-inspired RPi cases) has taken all of the drilling, cutting, and soldering out of the equation. Their case comes completely assembled. All you have to do is install your Raspberry Pi Zero or Zero-W in the cart (it has a pogopin connector), stick some AA batteries in it, and away you go. The design includes a safe shutdown switch, a microUSB port for firmware updates, and the cleverest L/R buttons I've seen on a GBZero. The GPi case is a bit smaller than an OG gameboy, but it keeps the original proportions and styling cues. It's a bit bigger than the bitboy, but more true to the original design and layout. It's not for sale quite yet, but review units have gone out to a few youtubers. I've included ETAPrime's review and teardown below. It'll be $70 whenever it becomes available, hopefully soon.
