The real loader is at $5500.  It accepts values in A and Y.
A is the starting track, Y is the starting index ($00, $30, or $70) into the read-address table (at $5400). The table contains three 00-terminated lists of addresses. You can see that it uses most of the memory. You'll need some trickery in order to preserve $BF00-BFFF, but the game runs in 48kb, so the ProDOS code in $D000-FFFF is safe.

Hm.  That's a start, certainly.

For Rocky's Boots I found a block of 256 bytes that wasn't used and held the ProDOS page there.

-uso.
