cool project, unfortunately doesn't work quite right.
There is still some work for a good windows port, while tyrian 2000 just works via dosbox.
Also, open tyrian game data is based on the older v2.1
OpenTyrian
In February 2007 the Pascal source code for Tyrian was licensed for a small group of developers to re-write it in C, in a project named OpenTyrian, licensed under the GNU General Public License. There are no plans of releasing the original source code. Following that announcement, in April 2007 Daniel Cook announced the free availability of his Tyrian artwork (not including the later work for the Game Boy Color edition and for Tyrian 2000) under generic liberal terms.[2]
Most recently, it has been re-released for the Nintendo Wii as homebrew. It is now a direct port thanks to a Wii port of OpenTyrian's hardware access, SDL.
This version uses Tyrian 2.1 data, instead of the later released Tyrian 2000.
OpenTyrian was built in 2 versions: Classic and Enhanced. Classic is designed to be play like the original DOS game. Enhanced adds command console, and uses alternate command line parameters (no legacy command line support).
