showgfx & editgfx

written by Rob Colbert (Saltine) & Dan Boris (Ouphe)

These programs allow you to extract graphics from Atari 2600 binary files
into a text file, then turn the text file back into a binary.


Usage:

showgfx file start length  (e.g. showfgx pacman.bin 0 4096)

        file - The Atari 2600 binary file you want to convert
	start - The byte you want to start from (typically 0)
	length - How many bytes to extract (typically 4096)

	This program will convert the binary file into a text file that will
allow you to easilly find the graphics in the program and edit them with
a normal text editor. The text will normally be displayed on the screen, but
you can pipe it to a file:

showgfx pacman.bin 0 4096 > pacman.txt

If you want to be able to turn this file back into a binary, be sure to
convert the entire image (start=0, lenght=lenght of file), and when editing
the file, be sure not to changes it's format.



editgfx textfile binfile (e.g. editgfx pacman.txt pacman.bin)

        textfile - Text file generated by showgfx
        binfile - Name of the binary file you want to create

        This program will convert a text file generated by showgfx back into
a binary file.
