Scene productions

Here are some of my contributions to the demo scene. Enjoy!

A Chipful of Love For You

I made a schlager chiptune for Gubbdata 2013, and it won the C64 Music compo! Read more.

First Day of Spring

I was asked to compose a tune to a chip disk, early in 2006, but the whole project appears to have been abandoned. So I'll just put my song here instead. Read more.

GCR decoding on the fly

The little routine presented here is, with all due humbleness, hands down the best code I ever wrote. It is esoteric and might not appeal to the masses, and it certainly has no commercial value. But in terms of personal satisfaction at a job well done, this is about as good as it gets. Here's why: Read more.

Gravazoid

llbit and I made a game. It started out as a weekend project, but we threw in a couple of more days of work to brush it up for the Game compo at Revision 2013, where it placed 2nd. Read more.

Hardsync

Named after one of the characteristic features of the SID chip, Hardsync is a C64 party game that follows in the (wait for it...) footsteps of games like Dance Dance Revolution and StepMania. Read more.

Humming-birds

At Dreamhack Winter 2004 there was a surprise compo (called the fast music compo) in which one had to write a piece of music using only the default set of sound samples shipped with Windows. Read more.

Klämrisk Hero

Yarrick and I party-coded this pinnacle of edutainment at Breakpoint 2010, where, to our surprise, it won the 96k game compo. Read more.

Kung Fu Goldfish

A fun event at Backslash 2007 was the 4 KB tracked music compo. My contribution was in the MOD format (ProTracker), which turned out to be quite a challenging restriction. Read more.

Parallelogram

Parallelogram is a demo running on the Commodore One extender board, which contains an Altera Cyclone III FPGA and an SDRAM chip. The logic design was made from scratch, including a homebrew CPU, FM synth and blitter with pixel shader support. The demo won the wild compo at Revision 2012. Read more.

Phasor

Phasor, like Craft, is a demo running on a custom minimalistic ATmega88-based demo platform. But it generates a composite video signal (PAL) instead of a VGA signal. Read more.

Phasor, high quality video

I am very grateful to Barta Zoli from Hungary, for building a replica of Phasor, making a high quality video capture and allowing me to share it with you on this site (and on youtube). Read more.

Power Ninja Action Challenge

Here's another ATmega88-based hardware chiptune, this time composed for Little Computer People 2009. It was my contribution to the "other music" compo, and won the 1st place. Read more.

Raster paper

This is a simple but very useful tool for C64 demo coding. It's a grid, 63 squares wide, that you print out on paper and draw instructions on. Along the top are helpful reminders about which clock cycles are involved in various effects, and which ones get stolen due to badlines and sprite fetches. Read more.

Safe VSP

I contributed this one-filer to the C64 Demo compo at Datastorm 2013. It ended up on 7th place, which I consider quite good for a technical proof of concept. Read more.

Shards of Fancy

Shards of Fancy is a C64 demo released in the Oldskool Demo competition at Revision 2013, where it ended up on 6th place. Read more.

Slaepwerigne

This SID tune was composed for Breakpoint 2009. It ended up 7th in the Oldschool Executable Music compo, which isn't too bad considering its original approach. Read more.

Spindle

Spindle is an integrated linking, loading and crunching solution for C64 trackmos. By hiding the details of the storage model, it allows the demo coder to focus on effects, transitions and flow. Read more.

Summer cloud

This is my first regular SID tune. It was written for Backslash 2007, where it ended up on 4th place. Read more.

The hardware chiptune project

Normally, when you create a chiptune, you start with an existing chip (such as the SID chip or the YM2149) and write a tune for it. We decided to start from scratch, and create a chip and a tune. Read more.

Turbulence

Turbulence is the successor of craft. It's a microcontroller demo based on the Propeller chip from Parallax. External I/O consists of stereo sound (at line level) and a VGA signal. Read more.
