RetroPie is a great emulation machine based on the Raspberry Pi. It has full VICE support, but was missing labels for the Commodore VIC20, C16 and C128. So I made some. Feel free to download them.

In a rush of nostalgia, I aquired the domain and now I've put Ghost Town on it for now. I want to put more stuff there soon, let's see how that goes...

I finally officially released Ghost Town JS today and I've been given the opportunity to write a "making of" story (in german language). Please visit and check it out.

After some heavy drinking at the BCC#10 demo party, I've now become a new member of demo group Mayday! Looking forward to be part of an awesome team.

Two new screens got released at the BCC#10 demo party in Berlin, "Moon" (3rd place) and "Love" (4th place). You can find them in the C64 section below.

Two new vector illustrations are up now, a SM124 display and a vintage TV set. Download them for free in the bonus stuff section below.

A JavaScript remake of the Commodore C16 game.

Visit the mysterious Ghost Town, a place full of unexpected dangers and hidden treasures!
Ghost Town JS is a JavaScript remake of the fantastic game written by Udo Gertz and released in 1985 for the Commodore C16, C116 & Plus/4. This remake is pixel perfect as it reads in the binary screen data from the original game. For more information and additional links, scroll down the page after launching the game. Have fun!

A C64 retro demo made in JavaScript.

awsm's biggest production yet, featuring 10 different screens with code & art made exclusively for this demo. Works best (and probably only) in a Chrome browser. If you can't get it to run on your machine, you can watch the video on youtube. The demo is listed on pouë

Launch demo

C64 cracktro remakes made in JavaScript

You can do a lot of cool stuff in the browser with the canvas element and some JavaScript. I recreated some iconic C64 cracktros as an exercise, using a library called CODEF.

Real Commodore C64 demos

After the positive feedback on "Full Of Sinus!" I was encouraged to give real 6502 assembler a try. These are the results. Click on the images to download the .prg file or visit the releases on

Scored 4th place at BCC#10, 2016. Another screen I started a long time ago, but only finished it in a rush just before the compo started. Some rasters in the border and top and border sprites to extend the lady to full beauty.

Love BCC on

Released at BCC#10 on Feb 27, 2016, this screen scored 3rd in the graphics compo. I made it almost a year ago and never finished it to the level I intended.

Moon on

Just a small PETSCII screen that plays around with the fantastic tune from Eddie. I decided to release it as is, knowing that it would never become 100% as I wanted it to be. Some raster bars and sprites involved.

Schaltkreis on

A conversion of the original screen from the Full Of Sinus demo. The picture got more colorful to compensate for the lack of a proper DYCP scroller and the zoom effect. I had a hard fight to get the raster bars stable.

Positive Karma on

My second PETSCII attempt. If you look long enough, you might notice that it resembles a postcard, with mountains in the back, the beach in the front and the logo being the hotels.

Vision Logo on

My first PETSCII logo. The main screen area is pure charset, but I opened the top and bottom borders and put some sprites in it to extend the image.

Nyanpetscii on

My first conversion of a screen from the Full Of Sinus demo. Minor tweaks on the image and a color wash effect on the logo and scroller to compensate for the lack of a custom font.

Look Mom, I'm an Eagle! on

My second C64 program, serving as request to get accepted as a member on You can see that it is still pretty much the same code that I used for the first demo.

Can I Haz Member? on

My first demo on the C64 after about 25 years. Nothing special by any standards, but very important for me to get back into demo development.
