This program is called "Alcohol 120%". It is a program which can handle the creation of 31 virtual CD and DVD-ROMs, letting users play discs without needing the physical disc. Users can copy CDs and DVDs to CD-R, CD-RW, DVD-R, DVD+R, DVD-RW, DVD-RAM, and DVD+RW discs. The reading speed of a virtual CD-ROM is 200x. It supports normal CD, DVD, and CD RAW subchannel reading methods.
The RAW reading method lets users emulate all CDs. Alcohol 120% supports numerous CD (CD-DA, CD+G, CD-ROM, CD-XA, VideoCD, Photo CD) and DVD (DVD-ROM, DVD-Video, DVD-Audio) formats. It also supports all current (ATAPI & SCSI) drives. The latest version adds two more profiles to the data type options and includes support for unusually formatted DVD+RW discs formatted by other software.
