Spriting help, for another game

There are five files from SaGa Frontier in the link above (they're all in a 7z compressed archive).  Each file contains a set of sprites, a palette, some garbage which makes no sense in the middle, a bunch of zeros, and actual monster data at the end.

I need someone who knows about this sort of thing to tell me where the sprites/palettes end, in each file.  That's it.  I know fuckall about image file formats, so I'll leave you with some Tile Molester settings:
4bpp Linear, Reverse Order
Canvas Size = Columns 32, Rows 16
