Let me add my 2 cents:

If an IFF picture is EXTRA_HALFBRITE or HAM, then the CAMG chunk is mandatory.

If the only bits set in the CAMG chunk are just LACE and/or HIRES, then
the chunk need not be included.

With respect to the ECS: The LACE bit does not necessarily mean to use
intelace mode.  It can mean "switch to interlace (flicker) mode" or it can
mean "do what ever is required to switch the display mode so that 400 or 
more lines are visable".  If the picture has 4 colors or less, I'd say the
latter.  But a 640x400 16 color picture requires interlace.  (Unless the ECS
can do more than what I've been told.)

Before we follow this particular thread, I wouldn't say anything more until
after reading the offical specs on the ECS.  It is really only 4 colors out
of a palette of 64 in the 640x400 non-interlaced mode?
