CDemu enables you to use disc images that contain more than a standard ISO-9660 filesystem, like .bin/.cue, .nrg, or .ccd images. It's needed only because mount can only directly handle .iso disc images, which can only contain a single filesystem, but many CDs have multiple sessions, mixed data/audio tracks, etc. In short you can mount nearly any kind of image file with ease using cdemu.


# pacman -S cdemu-client

This will install the dependencies as well.


To configure CDemu, edit Template:Filename. You can change the number of drives to emulate, the control device, and which audio backend to use.

Configure to run at boot

If you want start cdemu at boot add vhba to the modules and cdemud to the daemons section in Template:Filename.

To Run

First we need to check if the vhba module is present and working.

# modprobe vhba

We also need to start the cdemu daemon:

# /etc/rc.d/cdemud start

Commands and Usage

[From man]

             Loading a single image to first device:
             cdemu load 0 ~/image.mds
      Loading multiple-file image to first device:
             cdemu load 0 ~/session1.toc ~/session2.toc ~/session3.toc
      Loading a text-based image in non-ASCII/non-Unicode encoding:
              cdemu load 0 ~/image.cue --encoding=windows-1250
      Loading an encrypted image with password provided as an argument:
              cdemu load 0 ~/image.daa --password=seeninplain
      Unloading first device:
             cdemu unload 0
      Displaying device status:
             cdemu status
      Displaying device mapping information:
             cdemu device-mapping
      Setting daemon debug mask for the first device:
             cdemu daemon-debug-mask 0 0x01
      Obtaining library debug mask for the first device:
             cdemu library-debug-mask 0
      Disabling DPM emulation on all devices:
             cdemu dpm-emulation all 0
      Enabling transfer rate emulation on first device:
             cdemu tr-emulation 0 1
      Changing device ID of first device:
             cdemu device-id 0 "MyVendor" "MyProduct" "1.0.0" "Test device ID"

      Enumerating supported library debug masks:
             cdemu enum-library-debug-masks
      Displaying daemon and library version:
             cdemu version
