This is a quite interesting effect, considering the hardware:



I imagine a similar-looking effect could be implemented on the SMS using a fixed 6 colors background image (one for each lane, plus the background), and using raster interrupts plus midscreen palette changes for faking the scrolling effect (that is, supposing the SMS VDP could change 5 palette entries per scanline).

Nope, I won't try implementing the idea. :P

This is a work in progress racing game that uses real-time rotation and FMV on the NES:

This guy built a working video card only using OTS parts.

Make sure to check the follow-up videos as well, in the third one he actually hooks up that video card with a computer he also built out of breadboards and stuff.

And there went my whole afternoon. My girlfriend is hating me right now, I wonder if I should tell her what I actually did, or if it's better if she thinks I'm cheating on her 😁

Being interested in niche things is weird.

I remember seeing (some of) those videos about the VGA a few months ago - they're amazing!

RE3 game engine from GTA3 disassembly

In this repository you'll find the fully reversed source code for GTA III (master branch) and GTA VC (miami branch).

It has been tested and works on Windows, Linux and FreeBSD, on x86, amd64, arm and arm64.
Rendering is handled either by original RenderWare (D3D8) or the reimplementation librw (D3D9, OpenGL 2.1 or above, OpenGL ES 2.0 or above).
Audio is done with MSS (using dlls from original GTA) or OpenAL.

The project has also been ported to the Ni****do Switch, Playstation Vita and Ni****do Wii U.

Genius weird synth:

Sassy is an audio spreadsheet. Or, as it stands, it's THE audio spreadsheet.

It's a spreadsheet. You can add values to cells, ask it to average a range.

It's a synthesizer. You can ask it to generate a sine wave based on time, and output it through your speakers. Add an ADSR envelope, modulate the frequency based on MIDI input note, put in some filters and hey, it's an actual instrument.

Sassy includes over 100 functions, including some that largely make sense in a spreadsheet way (like finding maximum value out of a range) and others that largely make sense in a synthesizer way (like high pass filter, various waveform generators, delays etc) as well as a whole lot that make sense in both (like trigonometry).

Absolute genius, I am totally in awe. Also completely useless, so I am doubly impressed.
