I used Daemon Tools to create a BIN/CUE of of a game called Ultimate Yahtzee.
Having done this thousands (literally) of times before, I was surprised when dosbox informed me that it was unable to mount the image, stating that it was either not a cue/iso or it contained errors.
The game contains 6 audio tracks and one data track.
I then used daemon tools to create an MDS file pair, mounted it, and then attempted to write that mounted image to a cue file. Same issue. Thinking daemon tools might be the problem I then used MagicDisc to create a cue/bin pair from the original disc and the MDS files, but in both cases I got the same error from dosbox.
I tried instead creating an ISO and I selected the data track as the only output. Dosbox was still unable to mount the resulting ISO file.
At that point I took all of the files from the disk, copied them to my drive, and used WinImage to create an ISO from them. THAT ISO actually loads, but now I no longer have my audio tracks.
I've never seen dosbox blatantly refuse to load an image like this before. Considering it gave me the same error when it was just the data tracks, that seems to suggest to me that there is something odd about the file signatures on the games disc that is causing the disc images to become unreadable. Something about copying them off the disc and then making an image out of them bypassed this error though.
Any ideas? I attempted to mount the image using both the vanilla, emucr svn, and daum svn builds. Same error with all three.
