D.Y.S.P. using a cycle table

Introduction

This article describes a way to do a d.y.s.p. with eight sprites, using flexible cycle-wasting in the loop. This method differs from the $d017-approach in that we can use the full 21 lines of a sprite. Unfortunately this means our loop gets a little more complicated due to the fact that the number of cycles on a given raster line is now dependent on the number of sprites on that line.

Getting and assembling the code

The code is hosted at GitHub. It requires 64tass. Once you've cloned the repo, a simple

make

can be used to assemble to code into a runnable .prg file.
