+	   it's probably better than trying to read outside the file (it seeks to 0x6000 instead
+	   of the correct 0x2000 for the second half of the file). Could this be right
+	   or has it misunderstood the filesize somehow? My guess is that the filesize is
+	   hardcoded in to the game, and it never checks the filesize, so I don't know.
+	   Maybe it's wrong to return the seekposition when it's zero? Perhaps it wants
+	   the filesize then? - No, that didn't work either, it seeks to 0x6000 even if I return
+	   0x4000 from the first seek. */
