These are copyright 1989 Falsoft & Bill Burnico.  

They result in 4 8K files, each with a quarter of the screen (assuming
HSCREEN 2, which is the only one I ever used with this...)

I'm probably the only person who ever used this.  I'm afraid my
interest in graphics is rather occasional.

I believe I've seen a stand-alone save-as-MGE assembly routine that's
a slightly more standard route...

On my webpage http://www.sdc.org/~goosey/ I have an OS-9 utility to
convert the resulting file set to a VEF.  I have a newer version on a
half-crashed OS9 hard drive that knows more about palettes.
