Thanks for the suggestion. Explorer recognizes them as Audio cds and they all have one track that is 44 bytes. One of the games appears to be an echelon rip with the "e-" prefix so I'm surprised if it's defective. I burned from image in DJ 3 with the default settings if that makes any difference :/. I would appreciate if I could get a verified working image via ftp/icq/irc from someone to figure out the problem.
