The goal is to provide a Tool that can uncompress and decompress Cyberpunk save files. This is mostly a research project for now.

- The Program can decompress a save file.
- The Program can recompress files
- The Program can recompress modified files
- The Format of the uncompressed file is not fully understood yet.
- https://github.com/Atvaark/W3SavegameEditor could probably be a good starting point as the files seem to similar but not the same. It already provided a starting point for the LZ4 Chunk handling
- Modification can be done using hex editor of your choice
- Dont expect to be able to edit your saves easily until a later point in time.
!Backup your saves!
- Paste file path of file to decompress or drag file onto textbox.
- Hit "Uncompress"
- In the "Output" 2 Files will appear({guid}_metainf.json and {guid}_uncompressed.bin)
- To Recompress Drag the "{guid}_uncompressed.bin" File onto the textbox titled "Uncompressed File Path"
- If you changed the name or the paths changed you need to also drag the "{guid}_metainf.json" if not it gets added automatically
- Hit "Recompress"
- Test if it works ingame
