What I want to do is build a small computer to run just ZSNES and have it directly connected to my television through my video card, Ill use my controller adapter so esentially ill have a PC bases SNES instead of the original console. That way I can stick a 10 gig HD with all my roms on it and play. Hopefully I can find a small enough case that I can lay it on its side in the entertainment stand or off to the side without having the look of a big bulky box (hmmm maybe ill paint it with the original SNES colors).
Ok well back to the original question what recomendations for an optimal running ZSNES console

Right now my PC is a P2.8 1024 ram ati aiw raden 7500 im sure I wouldn't need something quite this powerfull for my project.
Your sugestions are greatly appreciated and very welcome.
thanx eh
