/* Zelda - TP Fix: It doesn't make much sense but it works in Zelda - TP and
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. */
