Good day.

I received a copy of college slam in the mail yesterday and promptly ripped it to bin/cue format. There are 55 audio tracks on the cd, so bin/cue seemed like the best choice there.

Anyways, I am mounting it in 0.74 using the following:
imgmount d ".\games\CollegeS\cd\college slam.cue" -t cdrom
(I have also tried the older command, -t iso)

I am able to go into dosbox, switch to my d: and install the game.

Launching the game however returns the error:
You need the College Slam CD in your CD-ROM drive!

The game compatibility page states you have to use the ioctl switch, however I was under the impression this does not work with imgmount (just mount).

I can considered copying all the files off the disc and mounting that folder using the ioctl command, but then I will loose the audio tracks. Any suggestions?

Thanks!

you might try using virtual cd-rom on windows,
and mount drive letter from that virtual drive using mount -t cdrom -ioctl

I suppose that is an option, but that also means I would have to manually mount this game every time I want to play it in dosbox.

I like to set all my dosgames up to run via a front end I built.

So far I have manged to get every game I own working without having to resort to outside programs. I'm hoping to keep the trend going.

Alcohol 52% FE include command prompt launcher.
So - just add "axcmd.exe /0: /m:cd_image_header" in the start of the .bat.

I need a virtual cd that can be run without being installed to the OS. Last I checked, alcohol requires installation. Does the new version run without being installed?

If it works with -ioctl and not and cue/bin pair, then that is a (minor) bug in dosbox, as a cue/bin pair should be the most compatible.

Is there a process by which I should report the bug? I do a lot of testing over at the scummvm project, and generally for something like this over there I would file a report on their bug tracker. Not sure how you guys handle it here.

I tested an SVN version and had the same issue.

The Dosbox bug tracker is at http://sourceforge.net/tracker/?group_id=52551&atid=467232 and I'd log real bugs there so they don't get lost in here.

the first step would actually to be confirm that it works with -ioctl. It might be specific to your copy.

The disc label is checked with a call to INT 21h/4Eh CX=8, resulting in a "no more files" error with an image mount. Even though the label is blank (spaces) there should not be an error. A blank label is returned with no error when the same image is mounted in Daemon Tools and that drive MOUNTed in DOSBox.

Until the issue is resolved the attached workaround program will satisfy the CD-check when mounting an image on the D drive. Source code is included in the archive.
