Dolphin help

Hey guys, Donkote here. I'm a total newb when it comes to emulators and roms.

I just have a small problem while running the Dolphin emulator. When I play Mario Superstar Baseball, sometimes the game won't fully load and the screen will just be black and Dolphin will freeze, crashing Dolphin.

The sound never works, its a constant buzzing sound.

When the game does work, (sound still doesn't work), the characters look all funky with parts of their body stretching around everywhere, will edit in with picture after.

Any help would be greatly appreciated, Thanks!
