A wrapper for the Aerowinx 744 Precision Simulator (http://aerowinx.com, also known as "PS1", a DOS flight sim) that executes the sim without emulators, and extends its functionality with advanced audio, input device and network capabilities.
A shareware game called begin was released in 1984: a tactical starship game with a good AI and fair rules (the computer had no advantage) I've hacked assembly code to make it a multiplayer game, so that folk can challenge each other rather than the AI.
