Building my own Retropie Mini Snes When I saw the Adafruit Pigrrl 2, I knew I had to build one with my 3D printer! It took a few days, but it was pretty sweet to build a portable Raspberry Pi gaming system with their kit. While it worked great with NES, SNES, GB and GBA games, it did struggle a bit with N64 games. So, I decided to look into building a more powerful set-top box to plug into the TV!
