I had a problem decrypting the files after extracting them from .mpk (I think its also possible to get it from loading the game in an emulator)
there are .2 files and files without extension
I saw there are zzz4 in the .2 files (not at the start) and not much from the other files
I already tried using the messiah BMS script but nothing really worked
some example files and extra files are here
https://mega.nz/folder/0HxBFaIC#uX8yXW0mlY_7n6uUgMBJaQ
the game is '???????'

Are you sure that's the right link?
There are many folders.
What are the exact two files you mentioned?

Code:

goto 0x20
get block_size long
get fsize asize
math fsize - 0x20
if block_size != fsize
    cleanexit
endif
get unk long
get fsize asize
savepos c_pos 
for i = 0
    get block_size long
    get unk long
    get zero long
    get bsize long

    set zsize = block_size
    math zsize - 0x18
    # Disorder (Messiah Game Engine) files decompressor
    getdstring ALGO 4
    if ALGO == "ZZZ4"
        comtype lz4
    elif ALGO == "LZMA"
        comtype lzma
    else
        comtype ""
    endif
    get bsize long
    savepos OFFSET

    string name = ""
    string name   i
    string name   "_"
    string name   ALGO
    string name   ".data"

    if ALGO == "ZZZ4"
        clog name OFFSET zsize bsize
    elif ALGO == "LZMA"
        clog name OFFSET zsize bsize
    else
        //ALGO NNNN ?????
        //log name c_pos block_size
    endif


    math c_pos   block_size
    goto c_pos
    if c_pos == fsize
        break
    endif
next i

tada!

Thank you! However, I used it as .bms and only got some zzz4.data, did I do something wrong? sorry for the inconvenience ><

ahh, I meant .2 as a format file, sorry I didn't explain it clearly! all the folders are just game files after decrypted from mpk

Did you worked the ZZZ4.data files out?I got into the same problem . And I don't know how to deal with that.I tried the messiah BMS script with ZZZ4.data files but nothing happened.
