Good time of day. Tell me what scripts you can open the file"tpkg" from Toyman, file ".zca" from Alawar and file ".pak" from Meridian' 93?



Toyman - https://yadi.sk/d/EBvpTEJgxEkRIw
Alawar - https://yadi.sk/d/ExRCr1xjPqQ6oA
Meridian' 93 - https://yadi.sk/d/ae_LVhHVCYbNzg

1)

Code:

# Toyman
idstring "tpkg"
get FILES long
get ZERO long
set OFFSET long 0

for i = 0 < FILES
    get ZIP byte
    get SIZE longlong
    get ZSIZE longlong
    get NAMESZ long
    getdstring NAME NAMESZ
    savepos OFFSET
   
    if ZIP == 0
        log NAME OFFSET SIZE
        math OFFSET  = SIZE
    else
        clog NAME OFFSET ZSIZE SIZE
        math OFFSET  = ZSIZE
    endif
    goto OFFSET
next i

2) Script is https://aluigi.altervista.org/bms/dancing_craze.bms but your archive xor'ed with other key.

3) Seems data is obfuscated.

So there is no way to open archive 3 at all? And a bit not understood with 2 archive. The script seems to open it, but in fact there is nothing.

Archive 2 > there is a script for unpacking this format, but need another xor key.
Archive 3 > data seems is obfuscated / encrypted.

In these two cases, reverse engineering is needed.
