tsunpack-csharp

A C# (.NET 2.0) rewrite of TSUnpack.exe, a utility for Microsoft Train Simulator that allows extracting Packaged Activities (.apk) files.

Packaged Activities are gzipped files that hold a pretty simple structure describing various files to extract at the root of the Microsoft Train Simulator directory to install a new activity: a new scenario that can be played on an existing map with existing vehicles. It is however technically possible to use a .apk to install absolutely anything onto the game's path.

A Kaitai Struct file is available in TSUnpackLibrary/msts_apk.ksy and has been used to generate the C# parser used by this tool.
