Some Comic Chat Background files not identified

[jsummers]

TrID identifies most Comic Chat Background (.BGB) files, but not the ones from the mschat25.cab file (link), e.g. volcano.bgb.

I think it looks for the right 6-byte header, but also for other things that aren't always there.

Indeed! Thanks for the info and the pointer to the additional file samples.
