Comparing byte order for Mac and Windows-created levels
=======================================================

An exit block:

Mac                     Windows

0070 0005 0000 1D14     7000 0500 141D0000 
Xcor Ycor Zcor 0001     6800 3900 6200 00 01 
0000 008F 0000 005D     0000 8F00 008D5D000000 
8D00 0000 2EE0 type          E02E0000 0400 

Data structure would appear to be

      Int16 Int16 Int32
      Int16 Int16 Int16 Int8 Int8
      Int16 Int16 Int48?
            Int32 Int16


A "normal", diggable block: 

Mac                     Windows

006E 0001 0000 1C11     6E00 0100 111C0000
0064 0064 0064 0001     6700 7100 6400 00 01 
0000 008C               0000 8E00 
0000 001C 1900          00191C000000
0000 1388               88130000

Data structure would appear to be

      Int16 Int16 Int32
      Int16 Int16 Int16 Int8 Int8
      Int16 Int16 
      Int48?
      Int32


"normal" block with right-side ladder:

Mac                     Windows


006E  0001  00001C10    6E00  0100  101C0000 
0064  0064  0064        6600  7100  6100 
00 01 00 01             00 01 00 01 
008C  0000001C1900      8C00  00191C000000 
00001389                8D130000 
008C  02 00000009 08    8E00  02 09000000 08 
0000296A                6A290000

If 4th line is like 6th line, then 

008C  00 00001C19 00    8C00  00 191C0000 00 

Data structure would appear to be

      Int16 Int16 Int32
      Int16 Int16 Int16 
      Int8 Int8 Int8 Int8 
      Int16 Int8 Int32 Int8 ?
      Int32
      Int16 Int8 Int32 Int8
      Int32

This suggests some changes to the structures for
diggable and exit blocks above!
