Just in case you haven't seen this, Gamasutra has picked up on a report from the US Official Nintendo Magazine, suggesting that Commodore 64 games may be emulated for the Wii Virtual Console. According to the rather fact-thin piece, "Although no specific titles were named, the only indications so far are of titles from now defunct U.S. developer Epyx, maker of the likes of Impossible Mission and the Summer/Winter/World/California Games series."
Doom on Xbox Live Arcade and now this? Just too much nostalgia. It's probably just a piece of highly creative supposition though so I won't get overly excited (and, of course, if I was less lazy I could get all this for free via emulation...)
