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