You can now mount bin/cue files! Daemon tools equivalent!

I've read several threads about bin/cue files whilst trying to find out how to mount bin/cue files in linux - like daemon tools does in Windows. I found out how…

But first - why do so many people think bin files are so many different things!?? I've seen numerous times people just saying "use 'mount -t iso9660 some.bin /some/dir'" - this is crap! (in most circumstances…)

So i'd like to set the record straight:

bin/cue files are paired.

The bin file is a raw image of a cd. A cd is composed of sectors (approx. 333,000 on a 74min cd) of 2352 bytes each. Different types of cd use different amounts of space in the sectors for actual data. A normal PC cd will use 2048 bytes per sector - the rest of each sector is given over to error correction. PSX/VCD cds use 2336 bytes, Audio cds use the full 2352 bytes with no error correction. Since bin files are raw data images, they are larger than iso files. The bin image can contain of any type of cd.
The cue file is necessary, it specifies the mode that a cd image is written in (see elsewhere for description of mode) and the number of bytes that have been read into the image per sector (normally 2352). Also index is specified. A typical cue file looks like:
```
FILE "image-name.BIN" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
```

Now for some useful info! The linux mount command will not mount a bin file. If you can mount a particular bin file then its an .iso file with a .bin extension. In my searches, I came across several handy utilities:

isodump - get it here: [url]/url

isodump will dump iso images from bin (CloneCD img) files. Its not perfect, and failed on one or two i tested.

cdfs - get it here: [url]/url

cdfs is a file system kernel module. You can use it instead of iso9660 when you mount cds. It will show all the tracks on a cd as files in the mounted directory, i.e. A data cd may show a single .iso file, an audio cd will show some .wav files (yes, it adds the WAV header!!), and a mixed cd may show an .iso file and an apple hfs image, and some .wav files…! This thing rocks!!

And now for what you've all been waiting for - cdemu. This is another kernel module, but this one creates virtual cd drives, just like daemon tools. A userspace program allows you to link a bin/cue file pair to a virtual cd device, and then simply use the linux mount command to mount the virtual cd!! Oh yeah, its here: [url]/url

So, now you CAN mount .bin files!!!!

You can now mount bin/cue files! Daemon tools equivalent!

also bin2iso can attempt to recreate cue files for single track data cds.

You can now mount bin/cue files! Daemon tools equivalent!

Just a tip.. If you have a SVCD thats in bin/cue format just use MPlayer to watch it.. no need to burn or mount…

mplayer movie.bin

whamma.. your in

For the record, I came across the following problems with cdemu: use the latest version, cdemu-0.5.3. If you're using Slackware 9.0, create a new directory for the cdemu.o module: [b]mkdir /lib/modules/2.4.20/misc[/b].

After you untar, make && make install it, run the [b]create_cdemu_devs.sh[/b] script included with the source. insmod the cdemu.o module (and edit your distro's init.d/rc.d modules file to insmod it on boot). Use cdemu as follows: [b]cdemu 0 foo.cue[/b]; this assigns the file foo.cue to device /dev/cdemu/0. You can use up to 8 devices (ie. /dev/cdemu/0-7).

Next, untar, compile, make && make install the cdfs module and insmod it (edit your init.d/rc.d modules file). Now you can mount the cdemu image as follows: [b]mount -t cdfs -o loop /dev/cdemu/0 /mnt/cdfs[/b], where /mnt/cdfs is your mount point.

You can also use cdfs to mount an actual mode2 SVCD as follows: mount -t cdfs /dev/cdrom /mnt/cdfs.

In using cdemu and cdfs, however, I found that although I could navigate the *.bin filesystem, I was unsuccessful in extracting the mpeg2 file. I found that bchunk and bin2iso were also unsuccessful in extracting the mpeg2 file.

I then tried [b]vcdgear[/b] for linux, and it extracted the mpeg2 file perfectly: [url]/url

D'oh; I spent all that time on cdemu and cdfs; oh well, hope this helps someone.
