NTSC NES / Famicom only. As official PAL machines have different PPU timings and we have to cycle count until the last line of raster effects :)

me like... I was wondering why NTSC as it makes live always harder or us PAL coders are lazy :D

Heavyweight release for an underappreciated platform.

Will battle hard for a high placing.

very glad that you've made it through all the production hell - sitll couldn't believe it's stock Famicom with nothing but a program and character ROMs on a cartridge, great design, and that olezha's music is just <3 <3 <3

very cool and impressive, especially considering maximally strong NES limitations

put together quite well, with a pretty good tune

For the tune, the wobbler, and the 3D objects along the text!

Really great stuff, at least from what I currently know about the NES. The best part is of course that it's all NROM - no bankswitching or IRQ.

Best Famicom demo I've seen, very nice work! Some of the best DPCM IRQ abuse around :-)

I'm quite curious about the 420 color screen, I understand what the code is doing but I'm not sure what I'm _supposed_ to be seeing. Composite artifact colors? Time-dithered blurring?

It's using a hardware bug/feature that if all rendering is off and VRAM port address points to the palette memory, it will display the color of that entry as a background color. This is why there's a big PPUADDR read slide during active display.

This effect, combined with color emphasis, had been discovered and made into a full color palette demo almost two decades ago. But nothing more had been done to it until now.

nice one!

natta: ah, I see. So you have 6 bits of palette that you're cycling through + 3 bits of emphasis, and filtering out redundant/invalid colors get you 420 colors total. Now it makes sense!

Excellent

Very nice demo with very cool effects for this old system. We featured it again on our "Best of Revision 2025" show which can be found in our recorded livestream starting at 00:33:50. English subtitles are also available. Subscription to our YouTube and Twitch channel is welcome. 🙂
