Compressed Unity files

Post by moonpaladin »

Hello! I'm still checking somes files that have in my drive. I found two types of Unity, are from the same game cause was in the same folder, as I remenber these uncompressed files I got from cache folder, while the others were packed in the base .apk. Anyone can help me out to decompress it? Thanks in advance!

They seem just a container for stand-alone files and not compressed.

Code: Select all

endian big
get DUMMY long  # 0x4e
get FILE_SIZE long
get DUMMY long
get OFFSET long
goto 0x4c
endian little
get SIZE long
get NAME basename
string NAME + ".dat"
log NAME OFFSET SIZE

No idea about the format of the content (except for the first 32bit string size followed by the string) because all the files seem to be different.
