CDEmu vs gBurner Virtual Drive

CDEmu emulates optical drives and discs on Linux, including CD-ROM and DVD-ROM media. Its kernel module provides a virtual SCSI host adapter that connects the Linux kernel with a userspace daemon, while libMirage gives access to many optical image formats, including MDS, CUE, BIN, ISO, NRG, UDF, DMG, CSO, GZ, DAA, and ISZ. Emulated media can be mounted in Linux, with automounting available. The project also describes experimental CD-R and DVD+R recording emulation, allowing blank virtual discs to be written with disc-burning software. Users can load and unload devices, check device status, and manage debug masks through command-line or GTK clients. The daemon exposes methods over D-BUS and can register on the session or system bus. System-bus use needs special permissions; session-bus use requires read and write access to the VHBA control device. CDEmu is free under the GNU GPL version 2 or later. The project lists official source tarballs and Linux distribution packages; third-party packages are not verified or formally supported.

gBurner Virtual Drive is a free Windows utility for creating virtual CD/DVD drives and accessing disc images without burning them to physical discs. It can create up to 16 virtual drives and supports formats including ISO, GBI/GBP, DAA, NRG, MDF/MDS, BIN/CUE, UIF, ISZ, DMG, IMG, and VCD. To mount an image, users open the virtual-drive tray menu, choose the mount command, select an image, and confirm. The same menu provides an unmount command. The download page lists Windows support from version 98 through Windows 11, including 32-bit and 64-bit editions. The free utility is listed at free and is described as free for personal and business use. However, the download comparison identifies mounting an image file to a virtual drive as a gBurner Pro feature rather than a gBurner Free feature. Pro costs $39.95, paid once. The maker says game and program images can run at over 200 times the speed of a conventional CD/DVD-ROM.
