Can't really help ya except to say that whenever I play CD games with audio tracks I always make a CD image and have DosBox mount that. That always works for me.

yes, i think as same way that DosFreak....perhaps some games intended for CD-Rom execution ....and requires played from original storing format...no Dosfreak?

for example, when the games comes with Audio Tracks in music soundscores.

Thaks a bunch for your advice, DosFreak. It's an ingenious way
to solve it. 😎

Thanks, Shed.

How could I make an ISO image from a mixed CD (audio tracks +
data track)? Clone CD only builds IMG files. On linux ccd2iso
converts IMG files to ISO files, but only If they have one track.
I've also tried with dd if=/dev/cdrw of=myiso.iso but in some
point it fails...

And I have another problem: t7g has 2 cdroms. When It
demands me the second one, How can I change the ISO?

One time I get the ISO I'll mount it on linux (mount -o loop
myiso.iso /mnt/loop) and use it in DosBox:
mount D /mnt/loop -t dir or mount D /mnt/loop -t cdrom

I know that is only the intro music, but It's great. Furthermore,
Why it works on Windows XP but not in Linux? Same HW, same
DosBox version...extrange, very extrange. Maybe a bug in linux
version? I don't want to reboot every time I want to play my
favourite game.😖

Best regards.

If you don't mind using windows, you can download a demo version of CDRWIN (creating images is not limited there). You have to make a cue/bin image. If you use the image in linux afterwards, you have to modify the cue file, since it contains an absolut path to the bin file.
In dosbox then mount it as:
imgmount d <my_iso>.cue -t iso

Thank you, I'll try it. 😁

You can also use ISOBUSTER (Windows prog) to create a cue/bin. I've only ever created .iso's in Linux so I'm not sure how you'd create cue/bin under Linux. Mabye K3B supports it?

It seems that ISO image files doesn't support multitrack CDs (i.e.
audio + data). A linux program called bin2iso converts a bin file
to a ISO file and a set of wav files (audio files), so I think that.

IsoBuster worked fine. It seems that If there aren't read errors
(protection) then an IMG file (CloneCd) is equal to a BIN file.
I've tested it with a program called diff and both files are
identical.

I've mounted the BIN file just like Prompt suggests and the intro
music has come to my linux box!!

What I could do when the game asks for the second CD? T7g
expects the second CD in the same cdrom unit (you can't
specify another unit or path). That's a major problem...😕

Thank you for your help!! 😀

No, you can't change images while running.
Some time ago (before 0.63) I made a patch (search the forum) that allowed this, but it will no apply to current dosbox source anymore.

Will this work?

Minimize or put DOSBox in window mode (ALT-ENTER).

Mount image for 2nd CD.

Return to DOSBox and press CTRL-F4 (Rescan). It probably won't work due to different label, though.

Never tried myself.

For images mounted with imgmount this will not work. But for images mounted at the OS level, this should work as well as it does with a real CDROM.

I meant mounting CD images using a virtual drive (which you can always mount under DOSBox with its drive letter), not imgmount.

I've tried several things. Using ISO files (without audio tracks)
you can do something like that:

1) $mount -o loop t7g_disc1.iso /mnt/cdrom
2) Edit dosbox.conf:

[autoexec]
mount E /mnt/cdrom -t cdrom
3) Play the game until it demands CD 2. Then:
$umount /mnt/cdrom
$mount -o loop t7g_disc2.iso /mnt/cdrom

4) Press CTRL-F4, as eL_PuSHeR suggests.

But in this way, we haven't audio tracks. That procedure
works fine with "The 11th Hour", i.e. "The 7th Guest II".

I need a program to mount bin files on linux (in that way we
would avoid the imgmount "inconvenience"). A program called
cdemu (http://cdemu.org/) can mount bin/cue CD images, but
It seems that only mounts the first data track, so It's the same
that mount an ISO file. It works just like that:

$modprobe cdemu
$cdemu 0 t7g_disc1.cue
$cdemu 1 t7g_disc2.cue
$mount -t iso9660 /dev/cdemu0 /mnt/cdrom

and when t7g asks for the second CD:

$umount /mnt/cdrom
$mount -t iso9660 /dev/cdemu1 /mnt/cdrom

Prompt, Can I ask you why your patch is not included in DosBox?
I think It's a great feature. For sure it should be in the DosBox
wish list. I've been searching that patch along the forum with no
results... Your code (modified for DosBox 0.65) would work on linux?

it wasn't included as I forgot a bit about it and it was a rather large patch. (At least I remember it that way.)

Well the patch was pretty much a hack and I found a better way to implement this, but I never had time to finish it.
But you are right, the original patch is not here anymore and I don't have a copy of it myself. If someone can post it I could probably update it.

yeah I remember that it wasn't very clean either.
If you have a proper way to do it, then it would be helpful. Although There aren't that many games that support multiple cd's (I don't own one). But perharps I stopped collecting when they were popular. 😀

That would be the top.

There are "quite" Dos games with several CDs: Under a killing moon
(4 cds), The Pandora detective (6 cds), Ripper (6 cds), The 11th
Hour (4 cds), The 7th Guest (2 cds)...

Prompt, if I can help you in any way (programming,
documentation,...), please, tell me how.
