When I was in my 20’s I bought a full size arcade cabinet (Double Dragon) that was in pretty rough shape. I fixed it up and converted it to a MAME machine. It was a fun thing to have but hauling it around during moves was too tough so I sold it.
A few years after selling it, I decided to build a smaller version from scratch.
I bought some bartop arcade plans online and built it out of MDF board.
It’s powered by a Raspberry Pi model 3 and plays perfectly.
