PrintScreen for VGA
This code turns the VGA screen into a 24-bit Windows Bitmap file on an SD card (assuming you have an SD card connected to the Propeller).

100 MHz clock
I believe it's possible to control timing at the clock level using 4 cogs (because instructions take 4 clocks each). Cogs can be synced using the CNT.
But, 12.5-ns clock is rather inconvenient! It would be nice to have even 10-ns increments in the timing.
I've done this by replacing the onboard 5 MHz crystal
with a 6.25 MHz crystal. Since the crystal simply plugs into both
the proto and demo boards, this is very easy to do physically.
6.25 MHz is non-standard, but I did find some from alltronics.
I used the counter modulator to toggle PIN#7 at clock frequency and measured result with o'scope:
80-MHz clock:
100-MHz clock:

Playing Card Game Framework for TV and XGA
This is a basic framework for playing card games. I've minimized the size of the resources, so there's plenty of room for code for the actual game.
This demo just displays random cards on TV.
A basic psuedo-random number generator is included. Also, the code for a variable # of deck shoe is there.

I really like the 1024x768 (XGA) tile driver (see 3rd Party or Forum Stuff). But, wanted to be able to easily resize and move the graphics window around. So, here are the modifications that do this:
