X68000

You like arcade perfect ports right? Oh ok, how about better than arcade quality ports with little extras here and there? Well then, I think you'll do just fine here. Sharp, instead of trying to compete with the dominating NEC computers, created a powerful machine targeted at gamers, programmers and designers (think of it as the Macintosh to PC-98's DOS).

This thing had specs near identical to arcade hardware of the time (Capcom actually used those to program CPS1 games), and the screen is perfect for them too. Plus you can use a SNES and Genesis controller if you buy the adaptor, or feel free to try some of the other perfectly good controllers made for this computer.

There a 90% chance that if the game is on here it's better than any other port.
