Oh, not sure I've seen that format before.  XRoar needs the same as MESS
- a raw headerless dump (actually it supports a 16 byte header in files
with a ".dgn" extension too, for compatibility with "PC Dragon" ROMs,
but it just ignores the first 16 bytes in that case).

You could try any of the coco* zips here (unzip first):

I guess I can add an "if file size is 8/16/24K + 2 bytes, treat specially"
rule to the rom loading logic...  Out of interest, do you know which
emulator that image actually works with?
