The Engineering Behind the Smallest FPGA Game Boy

❤️ Support me on Patreon:   / whatskenmaking   FunnyPlaying's GB Mini puts Game Boy and Game Boy Color games into a handheld barely wider than a cartridge. But how did they fit everything inside, and is it actually good enough to buy? In this video, I'll tear down the Mini, trace its hardware, dump its flash, and test its compatibility and accuracy. We'll see what works, what doesn't, and where this little FPGA handheld still needs some work. ⭐️ FunnyPlaying supplied this pre-release GB Mini for testing. My analysis and opinions are my own. These findings apply to my sample and the firmware tested; hardware and software may change. 🔗 Links Referenced in this Video FunnyPlaying FPGB Mini: https://funnyplaying.com/products/fpg...
