Hi i am new to DC emulating but i have got my emulator up and running. But i am now not able to play the game i would like - Skies of Arcadia. I have read something about a .cdi file but i don't know what that type of file is. What i have is a .zip folder full of other .zip folders. I would really appreciate help on this matter as i am eager to replay one of my favorite games ever. If any more information is needed i can supply so thank you for your help
