The .ARCHIVE files are ZIP files given by the PK file headers but I cannot decompress any assets from them due to errors occuring with no matter archiving program/plugin what I use, will someone figure these files out? LINK BELOW, files from the Android version.

It states that it's using the compression algorithm 34 which is custom.
The data starts with the byte 0x1b followed by the 16 bit decompressed size (so it's probably chunked) followed by the raw compressed data which is nothing like lzss/lz4 or other "easy" algorithms where parts of the original data are visible.

Ok then how would I extract it then? This file is also used in the Win10 build, preferably in versions newer than 3.18.12091.0, 2.11.1807.1002 and 1.9.1.50210.

Hello?

What answer should I give you?
You have data compressed with an algorithm that you don't know.
The only solution is reverse engineering it.

Darn, guess I'll RE the Win10 version to find the mechanism...

Main library is Solitaire.dll - used functions from ClrCompression library (FxCore package). By function names, you can see that this is from a series of zlib (possibly modified).

Code:

crc32
deflateInit2_
inflateInit2_
deflate
inflate
crc32
inflateEnd
deflateEnd

clrcompression.rar

Someone on Discord figured out brotli is the compression, I have no script knowledge so if possible can someone make a script for me?

UPDATE: Someone did, ask in DM.
