Template:Infobox Software Alcohol 120% is an optical disc authoring program and disk image emulator created by Alcohol Soft. It can burn CDs and DVDs and emulate ISO images as virtual drives.
It can produce a backup of a CD by either using the CD or an image of it. The software can burn more than one CD or DVD at the same time. It bypasses some copy prevention schemes, and supports image file types such as MDS, CCD, BIN/CUE, ISO, CDI, BWT, BWI, BWS, BWA, and others. Alcohol does not back up copy protected DVD movies, due to legal reasons. It also has special options for PlayStation and PlayStation 2 filesystems making the copy process of these discs a very easy task.
Versions of this software are blacklisted by certain software manufacturers due to its use in defeating copy prevention schemes. There are, however, 3rd party hacks that try to remove the blacklistings, involving modification of the system registry.
There is also a version without the burning engine, called Alcohol 52%. It can create virtual CD/DVD-ROM drives and run the backup, making a physical copy of the disc unnecessary. Alcohol 52% supports up to 31 virtual drives, which can operate at over 200 times the speed of the conventional CD-ROM drive. Legal restrictions prevent this software from producing backups of DVDs that employ the content-scrambling system.
