Research direction

Start with the attached sample.gd.renamed2.zip and the repository's reference CPU GDeflate implementation. Compare the sample's block count and tile size index with the data format expected by that implementation, then determine whether the RTX Remix .pkg data uses an unsupported format or exposes a missing implementation path. Done means documenting the format mismatch or producing a confirmed decompression result.

Description

I'm trying to decompress the content of RTX Remix .pkg file which is compressed with GDeflate and since I want my program to be usable on systems without a CUDA capable GPU, I decided to opt for the reference CPU implementation in this repository but I'm unable to get anything decompressed, I've also looked at the data format and noticed that some things aren't what they supposed to be (for example the block count is zero & the tile size index is set to 2) so I wanted to ask if this is some special nvidia format or if maybe the implementation here is missing something.
