Nabuko's Den

What method did you use to determine the COLU -> RGB mapping?

User-Defined color selection. It was prior to move the purples to the next row, without affecting much the colors of the common palette in the 2600/5200/7800 emulators.

 

I observed that there was a green row that was almost useless, similar to the other greens so i removed it. About the yellows, I like most the default yellow and orange in the default palette, rather than the TIA Default thats why I keep it, same with oranges; the next row, reds, became into a "salmon red" but still looks fine where the red was before. Purple was changed to red, thats where I started to swap the current color row with the next, until I reached the greens. Overall, It's almost the same palette but with slight changes based in the eye-likeness more than the acurracy of the system

It's pretty good, Nabuko. For the 8-bits the palette works great. However, I have to digress that it's not as optimal on the 7800. In games like DK, you still have a purplish skin tone (where as it's more of a flesh color when I play it on my TV), and Ms. Pac-Man (the official version, not PMP's collection update) still has a very purplish color (where as the maze and Blinky should be more of a red color, like how the box for the game shows). I'd say for that, leave it as it is. However, you might want to re-adjust it as something seperate for the 7800.

All your comments are welcome, complains too! But don't complain too much ^^

 

Yes, its right about DK. I never had Donkey Kong in cart but Donkey Kong Jr., and as far as I remember the color looks good, not like in DK where Kong and Mario looks "pinky" I think that color scheme was in part a "bad selection" of the programmers, Trebor noticed that, you're not alone. If weren't for the palette, the beams will still look purple and not red. Yeah, some colors cannot be changed or disappeared.

Understood, even so it's still a marked improvement. I applaud you for your hard work.
