How hard could it be? You put a micro motherboard into a game console-like case and make it look like a console, with only a power button, USB ports, and a cd tray in the front. On the back all you would need would be a s-video out port. When you plug it in you would get a menu that let you play games from almost any console, such as the NES, SNES, Genesis, 2600, N64, etc. Using authentic controllers wouldn't be a problem, since there's a USB adapter for practically every old console system controller available. Any comments? Has this been tried already?
that sounds like a modchipped xbox to me
Heh, my thoughts exactly. It IS a modded xbox. There are adapters, or DIY adapters for PSX controllers and all older controllers, plus it can play all the systems mentioned, play mp3s, videos.
I love the idea of an NESpc or similar to use as an emulation system, but an xbox is far cheaper, and works just as well, if not better. It's practically an HTPC out of the box.
