Post by phobosavenger » Thu Mar 11, 2021 4:53 am

I'm trying to get inside a file to create mods of the game Raiders Sphere but unfortunately I can't, the file type is * .dpd could someone help me with a script that decompresses the file?

As for PAC file, it was easy to figure out.
Here is documentation http://wiki.xentax.com/index.php/Raiders_Sphere_PAC

And here is tool to extract data https://github.com/bartlomiejduda/Tools ... AC_Tool.py


As for DPD file, it seems to be more complicated. Offset array looks encrypted and most of the files are compressed, so no easy way to extract until someone will figure out the encryption.

This has already helped me a lot :)
Anyway I thank you for the help

There is another pack file with more resources inside it only extracts half, so I just didn’t send you because there wasn’t time to upload

I managed to correct it, changing the decoding method from "utf-8" to "shift-jis"

Is the repack process very difficult?

Yes, I did the same on my github. ;) One of the file paths had japaneese characters in it and that's why this error occured.

No, it's not difficult, because file format for PAC archive is simple.
You can try to write repacker with some programming language like Python or use QuickBMS scripting for that.
Here are some tutorials explaining this viewtopic.php?f=29&t=22266
