was written to decompress a stream of incoming data from a serial
port, but I'm sure that could be very easily translated to something
else.  The compression was written in Java -- and there are conversion
routines to read images from gif/png so you could use screen grabs if
you don't feel like extracting the images directly.  It shouldn't
munge the images with dithering if you use a close-enough palette (I
based the conversion palette off of a YIQ color mapping, so AppleWin
screen grabs that are 560x192 should come back 1:1.)

Hm.  I *got* a compressor but I only know how to use it for SFX.

But if it's as I think, maybe another means can be utilized, something like an RLE or block compression, that's simple enough to implement on 6502?
