Animated rainbow text demo

Post by catmeow72 »

This is a demo showing rainbow text in which the hue is shifted every frame to create an animation.
This demonstrates real-time palette modification on the VERA.
This was my first Assembly program, which was ported from C.
Version 2:

Using palette modification to do this and not just modifying the text color attributes in VRAM? Cool!

Sorry, forgot that the zip command on Linux doesn't recurse into directories by default.
