I recently discovered a binary container file in a GameCube video game which I cannot unpack!

I asked around, and I was told that it is an archive with this exact file structure:

char Signature[8]; uint32 FileCount; uint32 Size; char Padding?[16]; FileDesc Files[FileCount]; struct FileDesc { char Filename[32]; uint32 Offset; uint32 Size; char Padding?[24]; };

But I cannot figure out how to write a working script in Python which can unpack this file!

Literally all I want is to unpack the archive and retrieve the files inside!

Here is the file in question.

Please read this article of mine: https://www.codeproject.com/Articles/5035/How-to-Write-a-Simple-Packer-Unpacker-with-a-Self

It answers you in C. But rewriting in Python is easy.
