Hmm, is it supposed to be like this? :)
(I've tried several different roms and I get the same result every time, Link is always below the screen and I can't get out of the treehouse)
Mupen64 on OSX (imageheavy thread, not for modem users)
I took some screenshots of Mupen64 in action on my G4/533.
It's slow as hell (compared to sixtyforce on the same comp), but way more compatible than sixtyforce.
Enjoy (or not)
