I had the same issue. My console was on 4.3E and latest cIOS, all NTSC Wii VC games were slowed down. To fix this, you need to load them via USB Loader GX and force the region to NTSC.
@Xdqwerty you are not dumb or stupid, you need to stop saying that, you are very smart, even about alot of things I have no clue about. We all love you here, like a big family.
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
