The Grinch (PS1) .bzz files

I wanted to look into the old Grinch game for PS1, and nothing I knew is able to open or extract them

I left a few of the level files if anyone can give out any pointers

BZZ

Hate to bump but I tried some tools for Bugs Bunny: Lost in Time which was by the same developer and nothing worked

Must have been an update to the format at one point in 2000

Format seems to be different for each game using it. In most cases data is compressed with custom algorithm.
AFAIK no other tools exist that can handle this.

I did a bit of work on these formats.  The BZZ headers do change slightly from game to game, but the compression algorithm seems to be the same.  One day I might combine all the header formats into one script, but for now you should be able to use this Python script to decompress the data in The Grinch for further analysis.  It's not perfect because the format is crap (i.e. it doesn't store decompressed size that I can see, no proper filenames or file types, etc.).
