‘CDEmu’ is an optical disc drive (CD & DVD) emulator for GNU/Linux. The main application is based on the command-line but there exists a GUI (‘gCDEmu‘), and under Ubuntu’s Unity desktop shell, the access to the GUI is provided through its own application indicator.
It has the ability to mount lots of popular disc image formats (.iso, Alcohol 120% .mdx/.mds, PowerISO .daa, Apple’s .img, Nero’s .nrg format & more), supports adding/removing multiple virtual optical devices (including changing the Vendor ID, Product ID …), built-in event notifications (can be disabled) and supports ‘DPM’, ‘Transfer rate’ & ‘Bad sector’ emulation (disabled by default) as well.
If interested, open your Terminal window and enter the below commands for installing it.
sudo apt-add-repository ppa:cdemu/ppa
sudo apt-get update
sudo apt-get install gcdemu
