The Simulator is a flight simulator by Ekotek Datasystems.
The features include
The GUI, sound, aeroplane physical model and user interaction were written in SuperBASIC and compiled with QLiberator. All 3d calculations are done in machine code. The worlds (of which there were several), with their coordinates and colours, are coded in text files.
Also you were only allowed to make 5 copies, although this can be got around by using Digital Precision's clone program or you can simply attach the disk image now available to QemuLator.
