Stray musings:
David Chess and I had a conversation back on the Hullabaloo about internal formats in the IMG resource (used for the Sims' thumbnails), which seems to be JPG (raw dump of resource has JFIF, not BM), but they do have masking, which we couldn't figure out. I almost wonder if they don't use 0,0,0 (normally black) as the mask color on the thumbnails, since Sims with black hair sometimes end up with streaks of the background color where their hair should be the darkest. This is worse on the family screenshot, which I can't find at the moment.

However, the TXTR resources are either Raw8Bit (which is bitmap, but not bitmap format) or one of the DXT flavors. In my somewhat limited poking around, the grayscale normal is Raw8Bit and the colored texture is DXT3 (which allows transparency).
