2.0  VMFPLAY

     The player VMFPLAY can be used to play VMF files. The internal help
     from VMFPLAY will be displayed when you start VMFPLAY from the DOS prompt
     without any commands/options.

     VMF player 0.82 N.W.O. 1998,1999

     Usage:

     VMFPLAY [/L][/R][/G][D:][PATH]FILENAME.EXT|Wildcard

      /L  - Loop file
      /R  - Set Low resolution mode
      /G  - View in grayscale mode

      Keys while playing
	  - Press Space to play the next file
	  - Press Esc to abort.

     The movie can be started simply by entering VMFPLAY FILENAME.VMF at the
     DOS prompt for playing one file or VMFPLAY *.VMF to play all the VMF
     files in the current drive and path.
     You can also specify the drive and path name. Like VMFPLAY A:\VMF\TST.VMF


2.1  Looping VMF files.

     A VMF file can also be looped by entering the following command before
     the file name. eg. VMFPLAY /L FILENAME.VMF.

2.2  Viewing VMF files in Low res.

     The V9990 file will be set in the 192*240 mode when given the command /R,
     normally it is set to 256*212.

2.3  Viewing VMF file in Grayscale mode.

     By using /G the file VMF will be played in Grayscale mode.
     This is only supported by VMF files saved in YJK mode.

2.4  Keys that can be used during playing.

     The SPACE BAR can be used the skip to the next file. Escape can be used
     to abort playing and return to DOS.

3.0  Creating VMF files.

     The player VMFCREAT can be used to creat VMF files. The internal help
     from VMFCEAT will be displayed when you start VMFCREAT from the DOS prompt
     without any commands/options.

     VMF Creator 0.8 N.W.O. 1998,1999

      Usage:

      VMFCREAT [/L][/Y][/N][D:][PATH]*.BMP

      /N  - Create VMF without Header
      /A  - Add frames to an existing VMF
      /Y  - Use YJK compression

      You can create a VMF file a BMP sequence generated from for example an 
      AVI file (Use an PC for this).
   
3.1  Create a VMF file whitout a header
    
     By using the /N command you can create a VMF file whitout a header.
  
   
3.2  Add frames to an existing VMF file
     
     If you want to make really big movies then you must use this 
     option. When you make a big movie the frames before saving will be very 
     big (96MB to make a 32MB (saved in YJK mode) movie). 

3.3  Use YJK compression
     
     Use YJK (Same mode as the SCREEN 12 mode of the V9958) to save a lot of
     disk space and to improve the frame rate.
     This will 'crunsh' a 24 bit BMP file with a factor 3. 

4.0  Screen formats supported by VMF.
    
     The BMP file must be stored in 24Bits format. This can either be saved
     in raw mode or with YJK compression.
     The frame size cann't be bigger than 50KB. The frames will be 2 or 3 
     times as small as the original BMP frame ,because the frames are saved 
     in 16 Bit or 8 bit YJK mode.
     A good resolution to use is 160 * 120 with 8 bits YJK.
