CDemu is a software suite designed to emulate an optical drive and disc (including CD-ROMs and DVD-ROMs) on the Linux operating system.

CDEmu consists of:

  • a kernel module implementing a virtual SCSI host bus adapter,
  • libmirage which is a software library for interpreting optical disc images,
  • a daemon which emulates the functionality of a SCSI optical drive+disc,
  • textmode and GTK clients for controlling the emulator.
CDEmu functionality

Optical media emulated by CDemu can be mounted within Linux. Automounting is also allowed.

The files for the current version can be found at the project's website.

CDemu was originally designed by a group of friends (Robert Penz and Justus Schwartz) as a patch for MPlayer that allowed mounting .CUE/.BIN files. After the patch was completed, they realized the simplicity, and wrote a module for the kernel.

Originally, CDemu was named Virtual CD, but this name had been previously trademarked, and the owners of the trademark requested that they not use the name.

As of June, 2007, development on CDemu 0.8 ceased and a rewrite was developed instead. Most of this work was done by Rok Mandeljc. This new version of CDEmu took another approach to the emulation by doing as much as possible in userspace. As of June 2008 it is considered to be mostly stable.


As of version 2.0.0 CDEmu supports the following image formats:

Most of MMC-3 is supported, which means proper emulation of a SCSI optical drive.

CDemu has the support for CD subchannels, CD-Text, ISRCMCN and ECC/EDC, DPM/RMPS. There is also some support for a limited number of encrypted and compressed image formats.

The developers are working on supporting as many major formats as they can, and they encourage users to submit patches to this end.
