Seems like quite an ingenious idea, hopefully Nintendo doesn't jump on them. The website is pretty confusing though. One version uses a CompactFlash card. So you can just copy a game from your PC on the CF card, and insert the card back into the device, and the game will play on an NES? Also, are they guaranteeing compatibility for all officially licensed NES games? I don't care about pirate games, only the official ones. Reading the site, it does seem to do all those things. Great product, although I agree a bit pricey.
