My guess was that they are over endian-fixed, as the Amiga is bigendian and so 
is the Mac, all other datafiles seem to be read correctly though (sound, 
backgrounds, text). I had a look at the source but it was not immediately clear 
where the endian conversions were going on.

I was of course assuming that the data files are normally little endian, but 
converted to big endian on big endian platforms - am I wrong?

Are there any tools to let me inspect the actors data?

Great, I'll try the CVS version of SDL.
