Digging Donkey Kong (for possible packing)

Here's the disk image I'm using: 
http://www.brutaldeluxe.fr/crack/DONKEYKONG.DSK

On this image, the track usage map appears to be:

00000000000000001111111111111111222
0123456789ABCDEF0123456789ABCDEF012
#    ########################

(i.e., tracks $00 and $05-1C, 25 tracks total, contain data.)

The title screen shown during load appears to be on part of tracks $0B, 
$0C and $0D, where it's upside-down and oddly interleaved but present. 
This screen can be taken out - it'll never be seen in a file crack anyway.

All the fullscreen images are inverted and weirdly interleaved, and 
there's 5 more:

15/16 (0F/10) = main title
18/19 (12/13) = level 1 (barrels)
21/22 (15/16) = level 2 (girders)
24/25 (18/19) = level 3 (platforms)
27/28 (1B/1C) = level 4 (pie factory)

(note that this isn't the original level ordering but all US releases are 
this way.  on the Japanese arcade version you ALWAYS play barrels, pie 
factory, platforms, girders.)

OK, so there's 6 screens of 8K each - 48K just for graphics - out of a 
total of 100K.  That's 52K of everything else... including sprites. 
Ouchamagoucha.  Maybe there's other redundancies?

-uso.
