 ;; Use the gameboy's screen to display the new programming

 ;; instead of a side window. This will make it look much

 ;; cooler and create a terminal-like effect as the game is

 ;; being reprogramed. To do this, use a fixed data entry

 ;; region in ram, and run a program that translates this

 ;; region into the screen. Every time this data entry region

 ;; is full, run a program that copies the data to the

 ;; appropriate region in memory. This will cost ~15 seconds

 ;; at the beginning to set up, and then should have minimal

 ;; overhead (~5%) for the rest of the data transfer, but

 ;; will have a good psychological effect for the viewer

 ;; since he can see that something is actually happening in

 ;; the game.

 

 

 ;; Symbol size and type.

 

 ;; use fonts from zophar's domain:

 ;; http://www.zophar.net/utilities/fonts/8x8-font-archive.html

 

 ;; Green font on black background for matrix look.
