Thanks, I'm working my ass off on this Nut's & Milk hack, finding and learning about all the data in the rom. So far I've been successfully crossing the bridges.

Q: Does anybody know what the story is behind those firey chicken looking things from the final DK level. that I made as the bad guys?? are the flamming pies? what going on there? What are they?

This is great information. I was trying to search through this rom for the music data so I could construct those sounds clips in another game.

Any clue where the Music Data is??

And to compinsate this BUMP here are some pics

Here's some notes I gathered about 'Donkey Kong(JU).nes':

Fig 1.1


+-------------------------------------------------------+
| Format: |
+-------------------------------------------------------+

-ah -al -nb -b0 ...[bN]

ah : high part of address in vram

al : low part of address in vram

nb : dc54hhhh
||||||||
||||++++-length of data
|||+-----?
||+------?
|+-------0=repeat b0; 1=read in new byte (up to bN)
+--------0=write in rows; 1=write in columns

b0 : first byte of data

bN : the last byte of data (only used if nb.c == 1)

The background collision is hard coded into the game...so no level changes withough extensive r.e. and asm hacks.

I was lookin at the Wikipedia article about this game, I was pissed when I was kid that Nintendo stripped the second level that was in the arcade version when they made the Nes version.

Donkey Kong was made in 1981, as an arcade game. Famicom came out in 1983, I think... followed by NES in 1985. The Famicom/NES version of Donkey Kong still says the 1981 date, so I don't know when it came out for those systems.

What year was Donkey Kong made? Wasn't it one of the first NES games? If it was hardcoded... wow, that would suck.

What methods did you use to try finding data, anyway?

Well, get a disassembler and watch for VRAM writes!

Wouldn't be surprised if the levels and such were hardcoded...

The original NES Version, yes.
I tried finding data, but I couldn't find a thing.
It seems to be compressed or such with a complicated doohicky. But why? o_O

Anyone else gathered up information about this?
