I had already planned to double the pixels to compensate for chroma subsampling. My typical formula for making GB videos results in 320x288, and the analogous formula for NES and Super NES videos would produce 584x448 or 584x480. But even that's not enough to keep YouTube from messing with flicker. ...

What these bits actually end up used for on other platforms with 4-byte sprite attribute table entries: On VT03+ famiclone : Tile number (3) On Super NES: Tile number, palette, priority. There's also a separate table for high X and size. On GBC: Tile number, palette, and monochrome-mode palette Othe...

45 KiB at 96 bytes per tile would mean 480 distinct tiles. This is still more than you get on NES, plus you can flip them (if the art style allows).

Also interesting to note the font on the keys of that keyboard, the official Nintendo Entertainment System font all laid out right there. :D For the record, that would be Corporate, digitized as Corporatus by Alex Rosario . For Super NES, use Univers, digitized as U001 by URW . Tweet by @FontendoU ...

12-bit color is possible on the Super NES. Set up mode 3 with 8bpp RGB332 ("direct color") on 8bpp BG1 and the least significant 1 red, 1 green, and 2 blue bits on 4bpp BG2. Add them with color math. With 60 KiB of VRAM available for tiles at 96 bytes each, you'll be able to put 640 unique tiles on ...

They already sold the cartridge? Because I'm really curious. That's the first modern NES game that really caught my attention and that I consider buying. But first of all I need to know a bit more about it. So, would you mind telling us a bit about the game or maybe uploading a video of the gamepla...

Do you have a twitter or youtube account with videos for your effects/demos/experiments?

That would require me to learn to produce appealing YouTube videos. This in turn would require a new topic.

I am wondering what is making the page loading so slow. It might be my server being not the fastest one, or the network transfer speed, or browsers just being unable to display large documents. The first two issues could be avoided by saving a local copy of the htm/txt file. In my experience, it's ...

One difference I know is that pseudo-hires allows mixing 50% sub with 25% main and 25% COLDATA, or 75% sub with 25% main. Another difference that might (I'm not 100% sure) be relevant is limits on how sprites participate in color math, including which sprite palettes can and can't.

In theory it'd be possible to make more sets of tables for scaling up to 2x, representing the left and right halves of an 8-pixel column scaled up to 16 pixels wide. I just chose shrinking for my NES demo for several reasons: it was a minimum viable product to get the demo out; enlarging would be ra...

A year and a half later, I got requests on a couple Discord servers to add a light source to keep the cels from looking too simplistic like ColecoVision or early monochrome Game Boy graphics. I did so, eating the tile cost of not flipping cels vertically. Is there an easy improvement I could make? L...

I acknowledge the deficiency that a minority of exhibits aren't built to executables for various reasons. Feel free to file issues about specific exhibits so we can discuss how to proceed. The anti-DiskDude tool is written in C to be run on a PC, yet not all PCs run the same operating system. If you...

If you have more to say about this topic, PM an active moderator.

DMA bandwidth is one byte per 8 master clock cycles, and there are 1324 usable master clocks per scanline (1364 total minus 40 for WRAM refresh). This makes 1324/8 = 165.5 bytes per line. There are 262 lines per NTSC frame, and you can use all* blanked lines for DMA. So if you have 224 visible lines...
