I love the Colour DMD.
What makes the colour happen? or is it all ready programmed into the ROM?

Simon.

ColorDMD only supply their products for games they have written code for. There is a final step where the installer has to update the ColorDMD with the most recent code for that game via USB. The display itself is a color display that is almost twice as big as the original DMD Display. The code is what produces the changes in color with the game software. It is a very "smart" system.
