Re: new technologies for developing on NES

There are several reasons that I do not, and will not, use a smartphone. You're well within your right to make this decision, and I have absolutely no intention of changing your or anyone else's mind, I'm just saying that technology is heavily focused on smartphones these days, so you're likely to ...

Re: Dots vs. Pixels

Is the term "pixel" really that confusing? Virtually everyone I talk to knows what a pixel is, so I was surprised to hear the very beginning of this video talk about how it can be confusing when the size of a pixel can change. https://youtu.be/AnEuk8Vj3w0 Is there anyone who finds the ter...

Re: Tiled palette quantization tool

All web browsers' javascript implementations have been compilers for at least the past ten years, if not 15. With Python, you're "supposed" to use Cython or Pypy, although I've heard there are people in looking into adding a JIT to the standard CPython implementation. There already is a J...

Re: Square colon notation?

Python has a similar (but not compatible) "slice" notation for arrays: a[3:6] // a elements 3,4,5 a[2:8:2] // a elements 2,4,6 a[5:2:-1] // a elements 5,4,3 a[-3:] // last 3 elements of a (python negative indexing counts back from the end of a list) a[-3:-1] // 3rd and 2nd last elements o...

Re: SNES fast sprite shrinking demo

I'm not sure your demo is working correctly for me in mesen... it doesn't looking like scaling.. until the last 2 or 3 frames. Otherwise it looks like distortion. Sort of like a coarse fish-eye lens effect - the center of the image isn't scaling but the edges are, so it looks like the edges are coll...

Re: Hi color image demo for PCE

I improved the process; more optimal color/dither distribution, and now increase horizontal resolution/detail. If you have a real PCE/TG16, a CRT, and preferably composite video - then give them a try out: http://www.turboxraypce.org/private/test_images_improved_conversion.zip http://www.turboxraypc...

Nothing fancy like that haha. No mid screen color updates or anything. Just plain ol' 4bit tiles and sixteen 16-color subpalettes.

Re: Tiled palette quantization tool

Can't the other tools do that already? I can convert the image with an existing palette, but how would the palette file look like? An image with palette colors, like my tool's palette output, or a text file with a list of rgb values? Yeah, take an input palette png like the one you output. I have m...

Re: Tiled palette quantization tool

What about the ability to give it an existing palette file and have it convert the image under that spec?

Re: Regarding 4:3 and 8:7. . . .

Games have always been plentiful with unused content, but you'll be hard pressed to find a game with some of the type of "unoptimisations" (as I like to call it) you can find in modern games. Huh??? I find found plenty and wasn't hard pressed. Just how many old games code have you stepped...

Re: Tiled palette quantization tool

What Gilbert said. That definitely sounds like some sort of memory saving or compression thing on the browser. Odd that it would be for the IO page but not the forum. Another good feature that would be nice to have, is that for the 'common' color, that it search the whole image for the more used col...

Re: Tiled palette quantization tool

MrJ — 09/05/2022 Using the tiledpalettequant site, pressing the quantize button twice after one another will get you two different “results”. I know that Mr J reported this, but I'm not sure on the exact details. So maybe there's something that's persisting (if you click the button twice instead of...
