Screen-Shader
Turns the colors of a screen into pixel shading patterns from eight UDGs, so a color picture can be dumped to any COPY-compatible printer in shades of gray.
SCREEN$
Screen Compress
Turns a SCREEN$ into a compressed, self-displaying block of relocatable machine code that redraws the picture with one RANDOMIZE USR, optionally embedding a title in the screen.
Sprite Demo
A machine code sprite engine gets loaded, patched with address data at runtime, and repeatedly invoked to animate graphics in a tight BASIC loop.
Extended SCREEN$
A machine code routine that supercharges the built-in SCREEN$ function to recognize UDGs, software graphics, and standard characters by their character codes.
Mike’s Notebook: CMPRES
If you are used to SAVEing SCREEN$ files, you may have noticed that the file size is rather large especially if you LOAD or SAVE using cassette storage medium. The file is 6912 bytes long.
