Thanks for the reply, however, I guess I'm not clear, at this point, on how the dat files relate to what I want to do.

I just want to recover or rebuild the binaries within the zip file for each game so that they run under MAME 1.05.

Since the PNG extension (within the titles.dat file) denotes a graphics file, am I even using the correct dat file in the first place?

Can clrmamepro even rebuild each games zip file with the correct (missing) bin files?
