Color Squares by KHS shows 16*14 squares of 12 different colors (plus black). On each frame, two adjacent squares are swapped. Assembler source code is Nintendo Entertainment Systemavailable.

24 Balls by KHS shows 24 16*16-pixel balls that bounce off walls. The balls don't flicker because there's never more than four of them (eight sprites) per scanline. (That's because there are no more than two balls per scanline at the beginning and all balls have the same vertical velocity.) The color palette changes every 8th frame.

Gradient Demo by KHS is a technical demo written in Assembler. It shows rapidly moving colors and text that moves in a circle (using a sine look-up table).

Software Mode 5 Mode 7 Effect is exactly what it tells!

This is a texture-map triangle demo for the Sega-Genesis/Megadrive.

This demo was written to demonstrate how easy it is to utilize the DS's hardware blending and create impressive effects with no effort. In this demo, the witch is flying in the sky, and whenever she's hovering between the moon, she turns black, because the light from the moon illusions it as such.
