>This background from Yoshi’s Island is made out of two layers, the cave layer and the star layer behind it. When Yoshi moves, the parallax effect causes the star layer to scroll relative to the cave layer. Certain isolated pixels in the cave layer are transparent, so that whenever they align with a star in the layer below, they become white for one frame, creating the illusion of sparkling.

What other cool tricks do you know that old games used to create unusual visual effects?

They didn't do anything all that fancy, but the amount of scrolling in this level always amazed me back then. Running full tilt from one end to the other is awesome.

That is really impressive, if you only ever played NES games.

The Apple II couldn't produce color. The signal it output was pure luma, with no chroma component at all. And it wasn't even grayscale, the luma was pure on-or-off, black-or-white. But certain patterns of extremely high resolution black and white dots produce colors on the CRT anyway as a result of quirks in the NTSC color clock system, and the Apple II exploited that.

I'll take I don't know what I'm talking about for 25 bucks bro. If there's no chroma, how in the fuck would NTSC color clocks even matter? What you meant to say is that the digital output (or RGB) is monochrome only. Composite by definition needs both chroma and luma otherwise it wouldn't even be called composite but ancient RF stuff from 70 years ago.

cycling color palette was a neat effect that was used a lot in the 90s. Also 'Mode 7', a faux 3d technique for drawing ground in games like Mario Kart was cool.

If It Moves, Shoot It! for DOS does some weird shit involving adjusting the screen's timing and changing the resolution which results in some unique screen splitting/moving effects for when you die in the game.
Honestly, I have no idea how the hell this works but apparently it does so only on real hardware.
