	I don't recognise most. The remainder look as though they are direct
copies of screen data. There are a few other formats you may want to
look at for example the GS filetypes $C0 and $C1. Then there are the
more interesting 3200 and GIF formats.

	The DHR file type may simply be an uncompressed copy of both the AUX
and Main memory areas put end to end. It may also be the data could be
placed so alternate bytes would be moved to alternate data banks. My
preference would be to arrange it so loading the file would put the area
going into the Main memory bank would be loaded in the appropriate
position. Specifically if HGR1 were used then the main bank would be the
forst $2000 bytes and tha AUX would be stored in the second $2000. For
HGR2 the two would be reversed. The same would apply to a double low-res
file.
