I can only advise to try all conversion options from here (http://www.lua.org/manual/5.3/manual.html#6.4.2) with string "DXT1", for example, find inoperative and inform maintainer of lua package.

"<L " means "native sized little endian unsigned long". maybe you are using a big endian or/and 16-bit platform?

let's try one byte:

I think that you are using the wrong Lua. try to test:

String files came with the release of the game. Anyone has any info on how to approach the new w3strings format?

ok, this is a "aes-cbc" from As3 Crypto Library ("aes-128-cbc" for quickbms) with key "47c2c1a998d1e94d".

"QuickBMS comtype scanner 2" does not give any readable results (with cutted "CENC" header) :(

any ideas?
