CDemu

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.

Installation

CDemu can be installed with the package cdemu-client, 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 (vhba-module) you must use the DKMS variant of the package: vhba-module-dkms.

Since systemd does not automatically load drivers for CD/DVD drives, you need to do it manually:

# modprobe -a sg sr_mod vhba

GUI

There are several GUIs available in the AUR.

GTK/Gnome: gcdemu^AUR is the official GTK version, which also provides a GNOME panel applet.
KDE: kde-cdemu-manager^AUR is the KDE equivalent which also integrates with Dolphin's Actions menu when right clicking an image file.

Examples

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 parsers:

$ cdemu enum-supported-parsers

gollark: Do NOT orient objects.

gollark: Denied.

gollark: You'd have to hibernate before unplugging it, of course.

gollark: I don't see why not.

gollark: Otherwise, technically maybe but I don't think it would be easy.
