Idk if its me or my emulator

[Magneto]

Hey everyone. Im new here. I hope im posting this in the right spot.

but anyway, Im having some trouble with my wii emulator. I downloaded it yesterday and I have the game, Tatsunoko vs. Capcom: ultimate fighting all stars. While the emulator runs and works, the game is a little slow and on the game, I can only see like parts of the character, like Ryu's head and hands only, or Rolls body except her mouth.

here are some images






idk if its just the rom it self or what. Can someone help

my comuter specs are (if necessary):

Toshiba Sattelite
3gb ram
Windows 7 64 bit processor
ATI Radeon X1200 series video card

thanks so much for your help
