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

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

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

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

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

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

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

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

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

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

    28 ;; will have a good psychological effect for the viewer

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

    30 ;; the game.
