Thanks. Have just had the chance to try it out now. Overall the game runs a lot more smoothly, but unfortunately, the music emulation is a little wonky, and this annoys me more than a little bit of lag now and them, so I think I'll go with the regular wii64 after all.

Can this use savegames from the regular Wii64? I'm playing OoT, and would like to see how much better it performs with this emulator.
