[HELP] How to unpack .pak from Mo Siang Online

Post by Scriptkiddie13 »

Hi, anyone knows how to unpack this kind of files using bms script.

.dat = Prius Online
.pak = Mo Siang

I already search for unpacker and tried all the bms script that can open .pak but no luck.

Here are some sample file.
Prius:

Mo Siang:

Thank you!

Prius Online:
It looks like it's just a raw container of aligned compressed files (0x00000001 + decompressed size + compressed data) so I bet there is an index file somewhere.
If you can't find the index file you can just extract most of the archived files with offzip -a

Mo Siang:
It's the same format used by Corum Online:

Thank you for the quick response, Im glad the bms script for Mo Siang works like a charm.

But with the Prius Online, I dont know what is the index file here.

I tried using offzip, I drag and drop the .dat to the offzip.exe and it generated Prius_unpack.dat = 0 kb size.
Honestly, I dont know how to use that.

Prius.idx seems the index file... a huge index file to be honest (usually they are few kilobytes).

You must use offzip with the -a option or the scanning feature will not work.

I would like to know how to use offzip or how to set it to -a option, if you have some link I like to read and learn ..
The link you posted above about offzip, I dont really understand how it work or make it work though I read it again and again to understand it.

Here is the index file:

offzip is a command-line tool, anyway I updated an existent script to work with this format of Prius Online:

Let me know if you get any error message, it should work very well.

Script 0.3.1

Remember that the script is experimental and the filenames may not match the content of the extracted files.
Anyway it extracts everything it's indexed so only the filenames may ("are" as I tested) a problem, in fact the latest extracted file will be texture\level\valleyofadamancy\lightmaps\terrains\00030004.bmp but the latest referenced files are texture\ui\territory\common_18thfield_valleyofadamancy.dds, updated.exe (again) and versionalias.txt (again).
There is nothing I can do.
