Project PiGear v1.0: Portable PI / handheld retro arcade system

After winning a few bids on a handful of busted Gamegears on ebay, I ended up restoring 2 of them (by recapping and swapping out some components). This is the result of the others.

This will serve as a prototype and reference for future projects, which will incorporate a custom designed 3D printed case, that will house the same hardware.
