If so, this could be interesting for you. Recently, several android-related projects convinced me to finally abandon subversion and move on to git -- new home for my projects is http://github.com/zirias. In the process of converting anthing I still want to preserve and share, I stumbled upon something I did during my years at university: A C64 demo written in pure 6502 assembly that mimics the AmigaBASIC demo "Music". Back then I thought -- this demo is nice, but even a C64 can do it when coded efficiently, so I started coding It's amazing what you can do with an ancient 8bit / 1MHz machine! So, finding this old svn repository, I made it build tonight with a recent cc65 toolchain and added the capability of creating a C64 disk image (.d64) directly with "make disk". The result is here, including a ready-to-use .d64 image. The only documented part is the code for drawing lines quickly, using only integer arithmetics. The core plot routine is blatantly stolen from Wollschläger's book about C64 assembly language So -- what do you think about this (if ANYone even read this far *g*)?
