I loved the simplicity of cart based gaming consoles. No scratched CD’s to worry about. Did it really matter if your kid wandered off with the game? Did parents even play games back then?
A modder from over at Instructables has taken his love of nostalgia one step further and dropped a Chinese Knock Off NES on a Chip (NOAC) into a Vintage Mario Brothers Cart. A couple of connectors and some mighty fine soldering later you have a NES in an NES Cart. Now that is recursion done right!
