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
https://github.com/hadashisora/BuggyBunny

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.).

do you know some about .xa audio files from the bugs bunny lost in time 1999 for pc version? any idea? , the unique info i know from this type file, is that, for example in audio data folder from game i found "speech.xa" so could be encoded in format ADPCM 4 bit, so what i did encoded a new file sound cleanest, im taked from ps1 extraction in wav format and sincronized in timeline im export with extension.vox a renamed in .xa, but didnt work, for case of the original file i tried decoded but sound not its very clean, be listening but with a lot of noise similar to a old radio, im import this original file in "audacity" to VOX ADPCM in frecuency 88200hz Mono for get audio sound in correct tempo, but sound contained these noises previously mencioned...  maybe this file it was encoded or encrypt with special codified for this game or maybe not ,really i dont know.. if you know something about types .xa files  im apreciated any  info .. anyway, thank.. for listen. im share this file speech_03.xa..
