HEY man, i have the exact same problem. and i tried to make it selfboot but i cant seem to copy the files from it. like when i load it in alcohol, it loads but wen i try to access it, i get the message that it might be corrupted. I get the i/o error wen i load chankast. maybe it might just be the file. Please HELP us cuz its driving me CRAZY!!! 3rd stike is the best Street FIghter EVER (IMO)
PS: No, its not becuz its in .cdi format cuz the other game i have, capcom vs snk 2 is in .cdi & it works real good!
