Emulator

hi everyone, well i have been trying to play star fox adventures on dolphin and i-ve seen on youtube that people are already playing this game on dolphin, so why shouldnt i give it a try, and i download the rom from http://128bit.me but the american version didnt work, neither the european or the japanese one, so i got upset but i found another rom for this game in emuparadise.me and it seems to work fine in the menu but then an error message pops up and says : ''verTo D3D : invalid type size combo 0, 4'' and another one saying : Warning: Illegal command 52
CPBase: 0x002cc6a0

Warning: GFX FIFO: Unknown Opcode
(0x52).
This means one of the following:

• The emulated GPU got desynced, disabling dual core can help
• Command stream corrupted by some spurious memory bug
• This really is an unknown opcode (unlikely)
• Some other sort of bug

Dolphin will now likely crash or hang. Enjoy.
so i dont really know what to do,

could someone help and tell me what should i do to fix this problem? cause i really want to play this game so badly , help please!
