JULY 6 - 8

  Atari competitions
The usual competitions for Atari demo/intro, graphics and music will be held. Demos that work on our compo hardware hardware will be run live while other Atari platforms will need a video recording to be submitted as well.
We will display full specifications of the hardware requirements as well as file size/resolution before it's shown.
Remote entries
You can send us remote entries via e-mail (use a suitable subject so we don't miss it by mistake). Please tell us in your mail which machine and compo the production is aimed for.
Send entries to:

The twist compo!

We've had some people asking for a special compo this year as well, and in particular one theme has been heard above the rest: THE TWIST COMPO.

The Sommarhack brass always listens to their faithful visitors so here we go, another special rule compo which should be easy to enter, but hard to win.

  • The demo must feature a twist
  • Must work on 512k RAM
  • Must work on Atari ST

Even if the hardware specs are set, the theme does have some openings to go in different paths..
