Can u maybe rather post the Hex dump or ideally zip up or post somewhere the binary file

unless it's some sort of simple XOR encryption that won't help either.....more information is required.....

Some files might be wrogly extraced, or they use hashes for some assets. I don't suppose that devs would name their asets like ´ò¿×.dds, also those 4 characters look axactly like 32bit hash.
csv files in games are ussually encrypted.
lua file is compiled script file, not encrypted.
dds file might be xor encrypted, since its visible that first 128 bytes are dds header, also I see repeating characters F9 F9 63 34 CC CF EA 87 where null bytes are ussually occuring, might be part of a key? Rest of image seems like DXT format. For this thing it would be nice to have more dds files.

the header looks encrypted similar to 256-bit blowfish i saw in some other games
samples not long ago, guess you need to find the key and identify the algo. :eek:
fortunately the image data doesn't look encrypted so you can still work with it. :D

i don't know what you ask here, i don't deal with stuff outside of textures and the occasional model or archive.
i can contribute nothing more to this thread so good luck! :]

given that the dds header are predictable zeroes, it seems to be a 64-bit encoding with a 0x40 chunk size, where the 'chiffre' is modulated. i'm not into cracking encodings either tho. just can tell obvious hex patterns. :)
