Yep, this is probably good enough. It looks better than I thought it could get o.o

Well, I'm not really sure how to make it better, without actually editing the picture (this includes something as simple as removing those red leaves to the left. Adding common colors between all of the palettes (like red for instance) makes the image look flatter, because of the lack of colors. If anyone has any suggestions on how to make it look better, please share them.

Which colors did you pick, so I can complete the file description page for the "all limitations" version? And do you likewise release your retouched version to the public domain?

Once I have this info, I'll post both a regulation conversion (no dithering) for Wikipedia and an optimized conversion (sharpened and dithered) for NESdev Wiki as an example of how a photo ought to be processed for NES display.

Sure. :)

Anyway, I've added the palettes to the picture, so that it resembles the ones for the Gameboy and Gamboy Color:

The colors in the palettes are the following:

0F, 06, 16, 02

0F, 16, 38, 30

0F, 08, 00, 10

0F, 0A, 18, 30

I hope this helps.

Why did you resize the image to 240 pixels high? None of the others on the wikipedia page are taller, and in practice the US NES won't show that full height anyway.

Besides, the ground rules for that article imply that the image size shouldn't be changed from 150x200 unless a particular platform can't display the whole picture:

These simulations are always up to the maximum vertical resolution of the given graphic mode or up to 200 scan lines, if vertical resolution is greater.


But thanks for the palette. I'll see what I can do with savtool.py --palette 0F1602060F1638200F0800100F0A1820 tonight.

At 1:1 size, I had to make a few changes to the palette because different colors were getting put together. Here's what I came up with:

0F 16 06 08 / 0F 16 27 20 / 0F 09 00 10 / 0F 0A 19 10

One is converted per Wikipedia regulation, the other sharpened and dithered for showing what's possible.

It might be useful to note that the original image is not a multiple of 16x16 pixels, so it feels like it should be ok to move the edges of the 16x16 attribute grid internally, perhaps indicated by explicitly adding padding?

Now that I finally have some free time, I tried my hand at it...

Palettes...
0f 07 16 26
0f 08 18 16
0f 18 21 16
0f 26 27 38

(with lots of dithering)

I think replacing the grey with purple will make the attribute clash a little less noticeable, but other than that, it's the best one in this thread so far.

And (to disagree with psycopathicteen) Tepples should replace the dark gray($00) with $16.

How about replacing the photo with an amazing pixel art parrot? :mrgreen:

Seriously, am I the only one who thinks all of these images suck? I know this was proposed as a challenge, but isn't that whole Wikipedia page nonsense anyway? 90% of the consoles listed there don't come close to properly displaying the picture, a photograph that has no business being in a video game console to begin with.

Isn't the whole point of that page precisely to show how much older hardware sucked for the kind of images you'd expect today? (hence using it to explain why the hardware changed like that over time)

Exatly, just like a large part of WP, it is pure nonsense.
