Arena Of Valor Zstd

Post by nix132 »

it's the game Arena Of Valor. after the update it uses zstd to compress the file. They all begin with "22 4A" . I don't know but maybe it used some dictionary... I'm trying to unzip it but can't find that custom dictionary. I hope someone help me. I can send some coffee. Thanks very much

I code a tool for compress and decompress this but you need to recheck the output when using compress option :)

Awesome. What do you mean recheck the output?

I have the .compressed file but AssetStudio still can't open the file.
Do I have to Hex-edit the file after compression or so?

Hope you can explain it a bit more,
