Just finished setting up a raspberry pi to be essentially an nes, snes, genesis, and n64. Bought some usb snes and n64 controllers from Amazon. Best money I've ever spent.
I was addicted to PTO 2 on Genesis as a kid, got an abandonware version for PC recently. Ita not nearly as daunting as it was when I was 12, still fun.
My dad rented PTO for snes so much that the rental place gave it to him. I think he still plays that game.
