Mario Kart: Tour (Closed Beta Test) *.ZST

Anything on this format? I think its ZStandard compressed given by the extension but not so sure...

I want to view the game data from the base game's ZSTs extracted, but these files are not easily readable/decompressable/viewable. Anyone planning to figure out the compression/encryption used in these files? They aren't UnityFS's (a_) or MSTXTs (b_) or PCKs (b_).

these ZST files are Zstandard compressed. I also tried to decompress but the dictionary is invalid. so if you find the dictionary they use to decompress lemme know

The game decompresses them with an unknown dictionary on bootup to AppData, luckily I ripped them, throw me a PM for them.
