About This Repository

This repository consists of the following components:

• PKGLib: A C# library for handling PKG files .
• dlang-sencompress: A high performance library for Sen no Kiseki Compression/Decompression written in the D language.
• SenCompressSharp: A C# wrapper for the dlang-sencompress library.
• PKGToolCmd: A simple C# commandline utility for extracting and packing of Sen no Kiseki PKG files.

The compression library component is implemented using the D Programming Language and is based off of my own PKG Compressor dlang-prs.

The PKGLib and SenCompress libraries are written in .NET Standard thus can be used with any .NET implementation such as Framework, Core, Xamarin or Mono.

Compilation Instructions

Compressor/Decompressor (dlang-sencompress)

• Install the latest version of Visual D: https://github.com/dlang/visuald/releases

• Add the DMD and LDC compilers to your System Environment Variables' PATH (in case they are not added).

• Open Dlang.sln with Visual Studio.

Note: Successful builds output in build directory. where the solution files reside

All C# Components (Wrapper, PKG Library, Commandline Util.)

• Install the latest .NET Core 2.X SDK.
• Compile dlang-sencompress (see above) for Win32 (x86) and x64.
• Open CSharp.sln in Visual Studio and build.

Adding the libraries to your own project.

Do note that in order to use the actual libraries in your own projects you do not actually need the D compiler.

Individual precompiled packages are available on NuGet; you will only need the compiler should you choose to contribute to the repository.

For more details see "Using the Libraries".
