It’s all thanks to the Twilight Hack which allows developers to run their own unofficial software on the Wii. Basically, the game “Legend of Zelda: Twilight Princess” has a bug in it and developers took advantage of that to load other software without Nintendo’s blessings. So far a lot of the software released has been technical or not very interesting to your average gamer, but Quake has been ported to the Wii, as has SDLMame (updated download) and other emulators.
I was excited at the prospect of playing Mame games on my Wii until I realised how much it relies on the host CPU. The Wii’s brain isn’t that fast a performer. I wonder how it would handle emulating an arcade machine and throwing sprites and stuff around the screen. Anyone tried SDLMame on it? (Apparently it uses Linux as a host OS to run SDLMame. That’s cool!)
