I think there is some sort of compression:

Code: Select all

endian big
goto 0x4a
get FILES long
for i = 0 < FILES
    get OFFSET long
    get ID long
    putarray 0 i OFFSET
next i
    get OFFSET asize
    putarray 0 i OFFSET
for i = 0 < FILES
    getarray OFFSET 0 i
    #math OFFSET + 4
    math i + 1
    getarray SIZE   0 i
    math SIZE - OFFSET
    log "" OFFSET SIZE
next

What should I do with the files it outputs?

They look like they are compressed too.

I used offzip on one of the files and I got some readable results but it also outputs another compressed file which I don't know what to do with and offzip doesn't extract.

There something I need to do?

That's the problem, the data seems compressed (or obfuscated?) and the comtype scanner had no luck with it.
