Just a quick overview of my setup for my hacked Playstation Classic console. I am using a 128BG Sandisk thumb drive along with a powered USB hub. Also Using The 8BitDO M30 gamepad.
My goal is to play 16 bit and older consoles on this device but there are lots of ways you can set it up for your own preferences and purposes. There are a ton of other devices that will run older emulators so this isnt a special electronic device, its just what I have.
