I don't own one of these (yet!) but I would really love it that when I do buy it that I'd be able to immediatlye put an NES emu. There is a "challenge" posted at www.gmini400.com where they say they are willing to reward anyone who is able to accomplish this task. Although no dollar amounts have been expressly mentioned, it'd probably in the neighborhood of a few hundred bucks. Whether or not that is enough is for you talented gentlemen to decide...prehaps the challenge would be enough. :P
For those interested, follow this link...
I don't own one of these machines yet and, really, before I do, I'd like to know if emulation is possible on it.
