Majora's Mask, in fact, runs perfectly fine on project64. If there's anything about it that's so inaccurate on project64 that it honestly ruins the game for you, then I seriously feel sorry for you and I question whether or not you're actually playing for fun. I played through the whole game on it and it was great. Also, it was nice being able to play it on a 65 inch HDTV and not have it be blurry or pixelated. Thank you, bluedart for that.
Then again, things like frame-buffer effects being a half second off don't bother me, but hey maybe I'm weird. I must be crazy, but things being slightly different that I would never notice unless it was pointed out to me just don't affect me at all.
