C64 Software

In my spare time I write C64 software.

If you would like to donate to help future projects then you can use the donate button below.

One of my projects was to convert the arcade classic Berzerk.

Berzerk Redux

There is also Music Studio 2, a PC cross-platform editor for SID music.

music Studio 2

All of the source code is available from:
Music Studio binary release.
Depending on the the software already installed you may need to download VC2008 SP1 libraries from Microsoft.
ACME sources with tweaks.
All C64 related sources including Berzerk Redux and Music Studio.

An example of FLD Parallax used in a game, this was reverse engineered from Tusari. Published in 1992 this was the first documented game to use FLD parallax, basically vertical parallax scrolling sections. The original game used mainline code without any IRQ/NMI action. The source was updated to use timed NMIs instead and make the screen use the full number of rows, indicating just how trivial it is to use NMIs for this job of syncing to the raster.
