Hmmm.... I could design a USB gaming console that had all the goodies, such as a ball and spinning wheel, for a PC to run those old games. Bet they would sell too!
they sell full size controllers ala the old arcades for PC's. Actually with a bit of searching, you can find everything you need, and put something like 4300 old video games and arcade games in one machine.
