Hi!.....ok....try to extract all tracks audio and data game from the .cdi image with isobuster and then use the Echelon method for cdda...it will work! To explain you how to use the echelon method is too long and i can t do that here! Download the e-selfbt.zip file with echelon instructions from dccopyworld site!
Good luck!
P.S. People over-complicate things
