This PiBoy is fully working. The Raspberry Pi is a 4GB RAM 4B model. I built it awhile back and just never really ended up using it much. The front PCB has been modified with ALPS switches, the same ones used in a GBA SP, to make the directional pad and 6 face buttons tactile. The rear buttons are 3D printed ergonomic ones that are far easier to press. The console has had holes drilled in the back for better airflow and the entire Pi has a copper plate heatsink. This thing does not run hot like a stock unit would. A ton of work went into making this run cool. The Mini HDMI add on board is installed. Also included is a 3D printed grip. She aint pretty.... but she works.... you will need to use your own AC adapter. Pretty much any Micro USB charger works fine. The only issue with the unit is that the flex cable that allows you to mount the Micro SD card externally stopped working (seems very common on these) so the SD card is inside of the unit. You can buy replacement cables still from Experimental Pi for $10. Copying games on can be done over Wifi, otherwise you need to pop the back off to get the SD card out to manually copy. Everything else is fully working without issue. No ROMs will be on the SD card.
