LibHac is a .NET Framework and .NET Core library for reading and editing file formats used by the Nintendo Switch.
The library can be used either from the attacked .nupkg file, or directly from NuGet.
Note: The uploaded file is a .nupkg file renamed to .zip because GBAtemp doesn't like the .nupkg extension.
