Genesis Project, Gubbdata 2016: "Nothing but PETSCII"

The winning demo at Gubbdata 2016 in Lund, Sweden: "Nothing but PETSCII" by Genesis Project. All made by PETSCII, rather than pixel graphics.

PETSCII is a pretty clever character set

[@ehliar]

Incredible that everything is PETSCII. But the music really improves the demo as well. Now we want the next demo: Nothing but BASIC 2.0 :)

[@johnsmith1953x]

That's impossible.

[@phonicsonic]

Fantastic demo! The one dislike must have a bad character ROM.

[@agpxnet]

Outstanding!

[@marcinborkowicz2557]

Unbelievable!

Great.

[@RobLindman]

there is a little more going on here aside from PETSCII. the smooth scrolling and color cycling and animation has to be assembler.

[@auletes]

But still no HiRes-graphics.

[@kevin12567]

Okay, so I'm guessing the smooth scrolling is done by moving the screen by one pixel row/column, then back to its initial position when it's scrolled one complete block and shifting all characters to the next row/column and repeating?

[@keithjonas3257]

@@kevin12567 of course :) but that is just an API that someone already wrote. Easy peesy.

[@C64Lover]

API? It's hardware feature to shift screen 0-7 pixels as welm as generate raster interrupts used to split screenmodes
