@MFA001, @FlamingRalph: I had made my own KOM extractor which can unpack and decrypt new LUA files. Unpacker part is almost the same as before but decrypter is much more complicated.
@cjh33108, @Parampaa: You can't open this file because you have to decompile/disassemble it first
What I already know: this file is used by some kind of LuaJIT VM, but I checked standard LuaJIT compiler and it generated files with different header ID.
