I'd like to do a quick hackomatic job on Donkey Kong, if possible, to make the first level girders red like the arcade instead of the current purple/pink. Anyone know which byte defines the level one girder color? Or is it more complicated than that? Thanks.

Haven't looked at the Donkey Kong code, but since Coleco's own system had purple/pinkish girders, I assume they did it intentionally. Maybe when they bought their DK cabinet from Nintendo for reference, the monitor was messed up...

I did a hack of Donkey Kong to make it look a tad better last Christmas break. The girder colors was one of the changes I made (among others). I just never shared it because there were already so many similar Donkey Kong hacks out there. I'd tell you where the byte is for the color, but I don't remember off the top of my head and I don't have anything in front of me to look at it right now. If I think of it, I'll post when I get home.

I was thinking the other day that it would be nice to hack the sounds in the game. I know a lot of people don't like the sound of the 7800 Donkey Kong, but I prefer those sounds over the 2600 version.

Hacking the 7800 sounds to the 2600? That's a rather interesting idea.

Ok, so here are a few color locations for you to play with:

Donkey Kong: 06D8
Girders: 0A08
Mario's Girl: 09E5 - 09F4)
Mario Standing/Running: 0B3F - 0B4F
Mario Climbing: 0B6D - 0B7B
Barrels & Flames: 09E4
Opening/Title/Inactive Score: 0673
Player Active Score: 067C

Keep in mind that if you want it to look like the arcade, the girder colors are a pink/purple/red rather than red. The closest color in the TIA palette in my opinion is somewhere around 56.

Here's the hack I did almost a year ago with my "interpretations" of arcade colors:

This game could really use some hacking to separate colors from the ladders, fire barrel, etc. Here's a mockup pic of what I'm talking about:

Even if a couple rungs of the ladders between those slanted girders needed to stay the same color as the girders it would still look better than all being a single color in my opinion.

Here's another... Mario is a bit more like the 7800 version and the girders are red. I don't like the red girders as much, but I like this Mario better.

Here's girders with the color 54, (slightly darker than 56 from my earlier post), and the newer mario edit. I think it's slightly closer to the arcade color.

The arcade version actually has two-toned girders; there's a highlight, which does have a magenta tint to it, and a shadow, which is close to pure red at about half brightness. Put together on a fairly low-resolution CRT, I think the effect is much more red than the various Coleco implementations, but still not completely red like your second-to-last screenshot. Most of the screenshots I've found on the net are also not quite as magenta as the one you posted.

Combining the two colors gives a color somewhere around hex CB102A, and I think that's where I'd start when trying to find a single-tone facsimile of the girder color. I'm not that familiar with the 2600's palette anymore, but the A51818 of your "Donkey Kong Arcade red" screenshot could use more red, a touch more blue and a little less green.
