Mario,
I think there's a minor error in the TIM document-
The CF flag is actually bit 3, with the pixel mode bits being bits 0-2;
it appears that modes are stored as codes (i.e., 0,1,2,3 in bits 0-2)
and the CLUT flag is a single bit (set/clear).

That said, I more or less figured out CLUT tables and file formats, but
I confess I don't understand the background stuff (the rest of this
connected thread).

Put simply, I am trying to load a 512 x 240 8-bit color bitmap as a
fixed background. It shows up where I expect if I load the corresponding
TIM file into TIMTool (as an aside, any documentation on TIMtool- it's
not clear to me at all what a "project" is, or how one uses TIMtool
projects).

Anyway, I guess the most confusing issue is the relationship between the
cell and background map structures, when what I have is the entire image
(basically, I just wanted display the image).

I've looked at the ricochet code, as well as Ed's samples, but to no
avail.  It seems to me that this ought to be simple, but....

TIA
