What's New ?
------------


2.04 (01/11/1999)
 - New compiler creates faster code
 - MMX Decoder: 25 FPS in PAL color on a celeron 333 (MMX code by Ewald Snel)

2.03 (21/10/1999)
 - Fixed bug in improved PAL decoder
 - Option to disable double buffering & DirectX Scaling (slow videocards)

2.02 (13/10/1999)
 - New improved PAL decoder (thanks to Ewald Snel)
 - New auto lock methode (Start Of Image): use the arrow keys to
   adjust the image position and then press 'L'. It works best when you
   move the image slowly to the left. As soon as you see a vertical blue
   line at the start of the image, press the 'L' key.
   If it doesn't work the first time, press 'L' and try again. 
 - Press F1 to see help about the hot keys. This information is
   decoder-mode specific
 - Press 'S' to toggle unencrypted analog sound mode
 - Press 'R' to dump the raw image data to rawdata.bmp. You can try to
   write a program to convert this data to a nice TV image. If it looks
   good, mail me the (C/C++) code and I will include it in this program.
   Contact me if you need more information.

2.01 (13/09/1999)
 - Faster PAL color mode (>20 FPS fullscreen Celeron 333). Use 'C' to switch
   to the old PAL color mode
 - 'T': toggle test register
 - Better vertical lock
 - Snapshot mode
 - Snapshots mode takes a snapshot every second (you can change this delay in
   the config file)

2.00 (31/08/1999):
 - New user interface
 - Config file to save most settings
 - Windowed (16 bit or 32 bit color) or fullscreen (800x600 16 bit color)
 - 'Always on top' option
 - Scalable window (uses hardware acceleration if available)
 - 'Aspect ratio' option
 - 'Force vertical lock search' option
 - F5/F6: decrease/increase brighness
 - You can still use the cursor keys to adjust the PLL value

1.01:
 - It's possible to select CANCEL at startup
 - Bug: SHIFT didn't work properly with arrow keys
 - Resetting BTxxx at startup
 - Default PLL frequency
 - 'White cross' polarity check mode uses the white '+' on the screen
   to detect polarity changes (select with F7). I know it's a bit cheating,
   but it works very well.
 - You can use F5 to toggle pause mode
 - You can _still_ use LEFT/RIGHT/UP/DOWN to adjust the PLL frequency
   Use F8 to disable auto lock mode.
 - Starting ccrypt before starting a TV program doesn't crash
   your computer anymore (It works for me)
 - Decode mode "Averaging 2" added

1.00
 - New FKEY commands
 - F1 is help

0.3:
 - color decoding works very well
   (thanks to Ewald Snel for the source code)
