|Donkey Kong (left) vs. Neo Kong (right) sans sprites|
I've patched the main sequencer to skip the game-play demo and go to the title screen, which flashes for a few seconds like the real deal. Obviously Mr Kong is made from sprites - 10 to be exact. Now it's time to undo the patch and at least get the game-play demo screen rendered. Here the code gets a little more involved and again there are some sections I'm yet to reverse-engineer. However, I don't think it's going to be a huge amount of work to see the main background for level 1 (a.k.a. the barrel level).
I've also got a 'define' in the source for which level the game-play demo uses. Obviously Mario's attract-mode movements aren't going to be suited to the other levels, but at least at a later date I can have each of the levels rendered without delving into the game-play proper.
