Yup, we got them. Apparently there's an issue there though, stupid thing lets people upload but not download...the heck?
Anyways, I don't see any inherent issues with the configuration. So, apparently it's a game-specific issue. You can enable DOSBox debugging so you can see all the commands and such in DOSBox, that might help. That way you can check to make sure that the CD is actually mounted. You could also try using a different drive letter for the mount. But if the CD is mounted and the game refuses to identify it, then it could be that the game has some form of copy protection, it's looking in the wrong drive, etc.
Unfortunately though, since I don't have that game, I can't really do any troubleshooting myself, so I'm not sure how else to help you out.
