   I started to implement ArchiveV2 a few weeks ago, but I didn't finish writing the tests. You can take a look at what I have so far here.

   Sorry, I am not really into rust:

   I added the dependency like this:

   [package]
   name = "gvas_test"
   version = "0.1.0"
   edition = "2024"
   
   [dependencies]
   gvas = { git = "https://github.com/scottanderson/gvas", branch = "archive-v2", features = ["serde"] }
   

   And then I try to parse ti file like this:

   use gvas::{GvasFile, game_version::GameVersion};
   use std::fs::File;
   
   fn main() -> Result<(), Box<dyn std::error::Error>> {
       let mut file = File::open("assets/Level.sav")?;
       let gvas_file = GvasFile::read(&mut file, GameVersion::Default)?;
       
       println!("{:#?}", gvas_file);
       
       Ok(())
   }
   

   I tried one of the example files in /resources/tests/Slot1.sav and it works:

   

   But when trying Level.sav I am still getting the same issue even using archive-2:

   Okay, I looked at the attached file a little closer, and I'm seeing a couple of issues:

   1. You will need to change GameVersion::Default to GameVersion::ArchiveV2 to activate the code path for the new file format.
   2. The file appears to be compressed with Oodle compression, which we don't have a decompressor for, so you'll still get Deserialize(InvalidHeader("Unsupported compression type Oodle")).

   If you're able to generate files with zlib compression, you should be able to read those with my branch.
