	SNAPSHOT.EXE - Multipurpose CDROM Backup Program


>>> PROGRAM DESCRIPTION <<<

   SNAPSHOT.EXE allows you to backup just about any CDROM disc on the
market today. This includes AUDIO, CDROM, CDROM-XA, CD-I, MIXED-MODE,
and (optionally) KARAOKE CD+G. It will also backup most of the game
console discs including Sony PlayStation, Sega Saturn, etc. 

WARNING: This program is NOT freeware or shareware. If you have not
purchased and registered the fully-functional version, then you have
an illegal copy.

NOTE: To backup a KARAOKE CD+G disc, you must have a Yamaha CDR100/102
or Sony CDW-900E recorder. These are the only recorders that allow you
to write the R-W subcodes required for CD+G discs. You must also have
another CDROM device that can *read* the R-W subcodes as the Yamaha
and Sony can only write these subcodes.

*************************************************************************

>>> IMPORTANT! PLEASE READ! <<<

SNAPSHOT will not copy...
  - Discs with more than one "data" track (rare).
  - Multisession discs.
  - Discs with the "data" track stored in an extended pregap
    of the first audio track. 

  I do *not* claim that this program is capable of copying every
CDROM on the market. It was not tested with every disc that you might
own. Please do not call me or send Email because you have one or two
discs (out of dozens or hundreds) that will not copy. I won't be able
to help you. Any Email of this type will not be responded to.

*************************************************************************

>>> GAME CONSOLE DISCS <<<
   
   When backing up any game console disc (PlayStation, Saturn, 3DO, etc)
   the following information applies...

   !!! THIS PROGRAM WILL NOT DEFEAT THE BOOT PROTECTION SCHEME!!!
   !!! THIS PROGRAM WILL NOT DEFEAT THE BOOT PROTECTION SCHEME!!!
   !!! THIS PROGRAM WILL NOT DEFEAT THE BOOT PROTECTION SCHEME!!!

   Please don't send me any Email regarding the defeating of the boot
   protection. I don't know how do to it and will not offer any advice
   on this subject.

*************************************************************************

>>> SUPPORTED DEVICES <<<

The following CDROM devices are currently supported...
  
  - Hewlett Packard 4020i
  - JVC XR-W2001, XR-W2010
  - Olympus CDS-615E (CD-R2)
  - Philips CDD522, CDD2000
  - Pinnacle RCD-1000, RCD-5020, RCD-5040
  - Sony CDU-920S
  - Yamaha CDR100, CDR102
  - Toshiba 3401, 3501, 3601, 3701, 5301, 5401
  - Plextor 4Plex, 6Plex

WARNING: Do not attempt to use SNAPSHOT/DAO to make CDROM-XA discs
on the HP4020i or CDD2000 recorders with V1.20 firmware (this includes
PlayStation discs). These recorders have a disc-at-once firmware bug
that cause them to write improper CDROM-XA discs.

WARNING: The Pinnacle/JVC recorders are very inconsistent at both
reading and writing CDROM-XA discs. Therefore, I recommend that you
don't record CDROM-XA discs on these models... sometimes they work
and sometimes they don't. The new RCD-5040 and XR-W2010 appear to be
more stable than previous models.

WARNING: All Toshiba 3501 drives made before January 1995 have a
firmware bug that causes them to improperly read audio tracks.
This problem can usually be worked around by turning off "jitter
correction". However, you will probably not get 100% exact copies
of the audio data if you do this.

>>> COMMAND LINE USAGE <<<

Usage: SNAPSHOT <datafile> <audiofile> <cuefile>
	 [/ID=adapter:id:lun] [/CDG] [/NJC] [/SPEED=n] [/SUBCODE]
	 [/BIN] [/MOT] [/WAV]
datafile  - Output filename for DATA track
audiofile - Output filename for AUDIO track(s)
cuefile   - Output filename for CUE SHEET
/ID       - SCSI ID of CD reader (default is first found)
/CDG      - Enable reading of CD+G disc subcodes
/NJC      - Disable 'jitter correction' when reading audio tracks
/SPEED=n  - Audio reading speed (default is maximum)
/SUBCODE  - Scan audio subcode for pregaps
/BIN      - Write audio file in Intel binary format
/MOT      - Write audio file in Motorola binary format
/WAV      - Write audio file in WAV format (default)

   The /SPEED switch can be used to change the reading speed of
the CDROM drive (not supported by all models). This can be used
to slow down very fast drives such as the Plextor 6Plex. If you
experience problems reading audio tracks, try lowering the speed
to 1x, 2x, or 4x.
   
**********************************************************************

>>> FORMAT OF /ID SWITCH <<<

/ID=adapter:id:lun

  adapter - adapter number of your SCSI card (usually zero unless you
	    have more than one SCSI card in your system).
  id      - SCSI ID of the CDROM reader/recorder.
  lun     - logical unit number (must be zero).

  Example: /ID=0:5:0

**********************************************************************

>>> HOW TO BACKUP A DISC <<

C:\>SNAPSHOT TEST.RAW TEST.WAV TEST.CUE /ID=adapter:id:lun

  SNAPSHOT reads the original disc from the specified SCSI device
  and generates two IMAGE files and a CUE SHEET file. The first image
  file will contain the contents of the data track, and the second
  image file will contain all of the audio tracks. You must specify
  both files even if the original disc doesn't have data/audio tracks.

  The CUE SHEET file describes the track layout of the disc. This file
  is used by DAO.EXE to re-generate the table-of-contents and subcode 
  data on the new disc.

  WARNING: The output files could require as much as 750Mb of disk space.

C:\>DAO TEST.CUE /ID=adapter:id:lun

  DAO.EXE will record the new disc using the files that were generated
  by SNAPSHOT.EXE
