I have no idea. I just played it on a micro and I never could pull off the combos with the crappy random rhythm you have to pick up I think almost instantly or you fail to make contact so I walked away from it. Maybe it's the emulator, maybe it's input lag caused by the tv, maybe it's a hair of a delay from the bluetooth controller. I don't think the emulator actually does frame skip. I think it does have sync errors with some games, they're working to clear those out. Supposedly beta5 fixed the sync problem with DKC some people are saying so far.
