Hello,
I've stumbled upon this forum when looking for a way to extract the game assets of the Mobile Game Tales of Link.

The image files all seem to be in .pck files and opening them in HxD this for example:


I've tried to fiddle around with it for a while but to no avail so i decided to ask for help on the matter. All of the .pck files in the folder i tried start with 01 00 00 00

Another issue are the sound files which are in .acb and .awb
I've tried some programs and scripts provided elsewhere but all of them say the decryption is not supported.


This is an example of the top part of one of the .acb files, they all start with 40 55 54 46

Also here an example of a .awb file (which seem to be used for BGM

again, all files checked start with 41 46 53 32

This is my first time trying to decompile App assets so i hope someone can guide me in the right direction.
I'll attach a few example files and hope someone can help me, i would really appreciate it.

Upload a bigger pck file.

For awb: http://aluigi.org/bms/awb_afs2.bms

acb insted starts with "@UTF" so I guess it's made with the CRI engine but don't know how to extract it

As requested here's a bigger .pck file, i hope this one works.

Thanks a lot, that's one file type less to worry about ^^

Hmmh, thanks for the information. i'll see what i can learn with this :3

EDIT: On the matter of the ACB files i found a tool called "VGMToolbox" which comes with a CRI .ACB/.ACW extractor which works. Just not sure if i'm allowed to link it here at all.

ok also in this case we have only one archived file so I'm not sure if the first field is a FILES field or a version.
Script:

Code:

get FILES long
goto 0x10
for i = 0 < FILES
    get OFFSET long
    if OFFSET == 0  # my samples had only one file
        get ZERO long
        get OFFSET long
    endif
    get SIZE long
    log "" OFFSET SIZE
next i

Ah! Thank you very much, had a bit of problems getting the script to work at first but it works fine now.

By the number of Files in the Assets of the game i'm quite certain that each .pck indeed is only 1 file. guessing Bandai Namco does not care much for putting multiple files into one archive.
