Here comes my Codef remake of Full Overscan screen by Omega released on the Omega Demo (Atari ST, 1988)

It was the very first fullscreen in ST history.

Unfortunately this fullscreen was really unstable, and only worked on some ST configurations under certain conditions.

Omega was a Swedish group, and this screen was coded by The Flying Egg (TFE). The Omega Demo came out on December 30th 1988, at the second SYNC convention, about one week before the Union Demo. Its scrolltext proudly announces the result of the whole year’s race: “no upper, no lower, no right and no left border”.

The routine was very sensitive, and The Flying Egg knew it. The scrolltext gives his advice to see it working: “if you put on the computer and lets it get warm, then put it of for about ten to twenty seconds. Then it will maybe work.” He also promised to explain “how to do full overscan, or as some people call it, no border” at the end of the menu scroller.

A few days later, the Union Demo brought a fullscreen that worked on every ST, but Omega stayed in the race: in the Cuddly Demos, The Carebears write that they have “seen some pretty good fullscreens by Omega and Sync”.

How it works

This screen combines all the earlier border tricks to remove the four borders at once. With all the borders removed, the visible area reaches about 413 × 276 pixels, instead of 320 × 200 in low resolution, but the screen memory is almost twice as big. Like the left border routine of TNT Crew, this fullscreen had no stabilisation at the end of the lines.
