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? :o Do I have to do something with alcohol 120%? Or something to do with echelon and the read bin thing.....help....:o

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.......

In the Official Chankast Manual, it says:
"This can happen with games which have been released by the group "Echelon". They added an intro in front of the actual game, which causes the emulator to crash. If you want to play the game, get the original and make a proper dump of it."

Make a forum earch and you'll find the way to make the Echelon ISO releases work
