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.
