SDLMame 0.125 - Performance Boost

hi folks,
first of all 1000thx for this great Mame-Version.:thumbup:
Unfortunately i need more performance. I'am not alone with this...i feel it ;)
Which options are the best to make mame on wii faster? (above all the sound should be better)

I don't think that yo can edit any performance options. I honestly wonder if this project is dead or not. Does anyone know how to configure the controller settings to allow a second gamecube controller?
