We have competitions for Atari demo/intro, graphics and music. We gladly accept remote entries. Anything that can be shown/played on the Atari XL/ST/STe/Falcon is fine. Stuff for other Atari platforms will be shown as a video rather than from real hardware. Full specifications / hardware demands of the demo, intro, graphics and music will be shown before it's shown/played.

We're also doing a follow up on last years game competitions.
