I found the address where I would need to hack this in - the entry point, 
413C, is JMP'd to from 7D1B (1 player) and 7D25 (2 player).

My first attempt at doing anything on the cutscene is 
http://1.buric.co/dk-l1gx.dsk.gz which contains the level 1 stage graphic 
(as AFTER), and an attempt at recreating the backdrop for the cutscene (as 
BEFORE).

At http://www.fitz42.net/dkong/games/dkong/dkong.htm you can see a couple 
shots of what it is supposed to look like (I tried to make it blend in 
with the game as it already exists).

Kong climbs the ladder with Pauline (some of this code is already present, 
as this animation is already in the game as it is), sets her on the 
platform, then stomps, causing each girder to bend down into the shape 
seen in level 1.  (The ladder pulls up behind him.)  Finally, it plays 
the "grumble grumble" sound (which is also played at the end of each 
level).  This animation is only shown upon starting a new game, so hacking 
it in from 413C is probably a good enough place.

The BGM for this is the "dum-dum-dum-dum-DAAAAAAAAH", like in the Dragnet 
theme, or TUMS commercials.

There is no need to have the full code to this resident; some of the 
original setup code can be replaced to load it and then the code itself 
can sit from A700-B6FF.  Probably a lot of what is needed is already 
there, as the climbing animation is used in all but the last stage of each 
level.

-uso.
