As I understand it this has already been done for several systems. The first time I saw such a device it was one of those bootleg "100 Games In A Joystick" things that Ben Heck tore apart because it contained a glop-top "NES on a chip".

The MiSTER Pi set me back $180 and is perhaps my favorite purchase of 2024. It'll run almost any system made before the year 2000 and the gap is rapidly closing for lesser-appreciated consoles like the Saturn and Jaguar. This represents a tremendous value; it's hard to argue with that kind of money for an entire century of gaming. I heartily recommend picking one up.
