well i got the ".CDI" image file from coolroms.com... also tried emuparadise and extracted the .rar files and tried that as well...didnt get much progress....out of the 25 discs i bought...4 of them i got working from just burning the image (gauntlet legends, sonic adventure, RE2 Disc 1.. and code veronica disc 1) all the others were a complete failure and i threw em all away =/
