I'm sure all of you know how terribly slow many of the newer games run, as well as some of the oldies.
The problem is emulation. Sure, your brand new 2.4GHz processor might be hundreds of times faster than the old games, but it doesn't have the same circuitry as a game CPU, so it has to emulate it. This can take several more processor cycles than the original, making the emulated version slower.
What I propose is to use the actual CPUs from the original games to perform the nessesary calculations. The computer will still be responsible for loading roms from the HDD, controller inputs, AV output, and system RAM.
The extra hardware will be a circuit board with dozens of classic CPUs on it, utilizing either PCI or USB2 interface.
Depending on the game, some of the load will be assisted by the system CPU, taking over for some of the CPUs that emulate best.
Well, what do you think? Is it feasible?

I hope this will revolutionize MAME!
