The products

Over the years of development projects, some products have been released. This section is grouped by project and also listed separately by product title. The projects started in 1988 on our first computers, which were Atari STFM 1040s. You can find more detailed information in the projects section.

The Atari ST Products

On our first project, we quickly learned to code some simple programs. Matthias mainly focused on medium resolution programming and Stefan on high resolution. As 12-year-olds, the type of software we wanted to code was games, although we also coded some nice tools.

• International Kegeln and Bowling (1990)
  Our first release ever. Idea from Matthias (Olympic Arts) and first graphical coding project. The result was a complete Bowling game as a second version of "International Kegeln" simply called Bowling. It was complete, but never playable.

• Runner (1991)
  An all-round helper tool including a database, memo, system overview, and a game. Main idea from CPK and some help from Stefan on the built-in Hangman game.

• Atom Oh No! (1991)
  The second game release on the Atari ST completely coded by Stefan under the pseudonym "Tropic DREAMs". The idea came from the game Atomix on the Amiga, ported to the Atari ST high resolution 640x400 including a level maker and 10 demo levels.

• TOP Tools (1992)
  Some small tools and a game coded by Stefan under the pseudonym "Tropic DREAMs". All-round tool like Runner, a simple strategic game, and an archive tool for the Atari ST magazine TOS.

The PC Games

In about 1992, Matthias and I bought a 486 Intel personal computer and quickly learned to develop on this processor. Our main language was Turbo Pascal with more and more inline assembler from Stefan. The first type of software we wanted to develop was games.

• Glücksrad (1993)
  The first PC software release in 1993. Code by Stefan, graphics from Matthias, and PC-Speaker sound sampled from the 'Wheel of Fortune' show on Sat1. The idea, of course, comes from 'Wheel of Fortune'. Recommended computer: 486 with DOS. ... download (400kB)

• Tetris (1994)
  Fully playable two-player Tetris competition preview. Complete coding and graphics by Stefan. Never finished a release version, but this version is very playable. Released under 'SkyLINE Production'. Recommended computer: 486 with DOS. If someone could run it on Windows, please let me know.

The PC Intros and Demos

Matthias and I always looked at the famous PC demos and thought about the way to code them. Several small demo releases deserve mention.

• phobia-intro (1994)
  The best intro ever coded by me (Stefan). Some parts are faked, but it looks really good. I will try to make a screenshot soon and put the source and the executable into an archive for download. Meanwhile, you can read about the PHOBIA and the demo group story. Sorry, the links on this page do not work. ... read more

• Copperintro (1995)
  A really interesting demo with more than 100 colors in text mode done with Amiga copper-like effects. Only works on an old 486 PC. Perhaps it will run under Pentium, too. Just test it. ... download (10kB)

The PC Tools

• DOSMENU II (1994)
  The only boot selector that could change config.sys and autoexec.bat parameters while booting. There has never been a tool like this. It might be useful for you. A must for a DOS machine.
  ... download (170kB)
  ... free reg-key by email

• misc Tools (1995)
  SkyLINE released even more tools, especially the XLIBUNIT for Turbo Pascal for direct VGA functions. I will release the source code as public freeware, not sure if anyone would need it. Mostly assembler code, maybe just for fun to read through :)
