Chankast help!!!!

Ok well I might have to use the search button and stuff but I'm confused.....
Ok well I downloaded the Chankast emu and then I downloaded the Daemon 4.00. I also downloaded the Marvel vs. Capcom 2 rom and I mounted. When I start the game the dreamcast logo comes out. Then some window pops up with error ioControl. Can anyone tell me what to do to fix this? Do I have to do something with alcohol 120%? Or something to do with echelon and the read bin thing.....help....

Oh and I tried to to use Daemon 3.29. It worked but too slow so I used capcom hack. Then it frequently crashes. Sometimes when I don't use capcom hack it works. But it's still slow and it crashes again.......

Yeh i know it was a bit head scratching but i reckon you could use alcohol soft just search for it in limewire(p2p network) or google.
