CDemu is a software suite designed to emulate an optical drive and disc (including CD-ROMs and DVD-ROMs). It enables you to use other disk image formats that contain more than just the standard ISO-9660 filesystem, for instance .bin/.cue, .nrg, or .ccd images.
mount can directly handle only .iso disc images (which contain a single filesystem), but many images contain multiple sessions, mixed data/audio tracks… In short, cdemu enables you to mount nearly any kind of image file with ease.
CDemu can be installed with the package , which provides a
cdemu-daemon.service that can be enabled and started. If you are using a custom kernel, instead of the normal
vhba kernel module package ( ) you must use the DKMS variant of the package: .
Since systemd does not automatically load drivers for CD/DVD drives, you need to do it manually:
# modprobe -a sg sr_mod vhba
There are several GUIs available:
- GTK/Gnome: AUR is the official GTK version, which also provides a GNOME panel applet.
- KDE: AUR is the KDE equivalent which also integrates with Dolphin's Actions menu when right clicking an image file.
