"Finally, those stalwarts who refuse to "upgrade" from their trusty Commodore 64 computers can experience that hot new game, Prince of Persia. Homebrew developer mrsid ported the 1989 game from its original Apple 2 version, making the cartridge image available for download from his site. If you have a C64 or 128 and a flashable C64 cartridge -- or, more likely, if you have a C64 emulator -- you can check out the achievement.
The rest of us will have to settle for this video, which looks remarkably smooth for an unofficial port on such an old system. It drew the attention of Prince of Persia creator Jordan Mechner, who commented to say "I'm amazed and humbled by the amount of work this must have taken."
That's kind of awesome. That's some serious "just because I 'm a geek and can do it" cred!
