Help with Soul Calibur 2 Pal version

[Painguy]

i was playing soul calibur on my wii the other day,and i was thinking.....hmmm how cool would it be to play this game in 720p or even at 1680x1050. It looks good right now so it should look great in HD. so i load up dolphin and all it shows me is a black screen. im using the PAL version with SVN r 3932. All i get is a black screen. i dont want to conver the disk to NTSC because if something goes wrong my game is gone, and i know i can back it up from my wii, but the GC dumper i have is slow and it either fails all the time or is rly slow. How can i play this game???
