Hey Guys,

today I decrypted a Nintendo 3DS Game and found MAAAAAANY scripts and code-related stuff as plain text in it.
The Game I've decrypted was "Harvest Moon A new Beginning" for 3DS.
But the Game contains some xbb-files which are encrypted or compressed and I don't know how to decrypt/decompress them.

I've uploaded some and hope, that someone could help me with it.
I want do decrypt/decompress them. I think, they're compressed/encrypted on the same way.

Would be great if you can help me with it

Is someone able to help me with this? :/

Someone sent me a txt-file with informations about xbb files from an older Harvest Moon Game.

I really want to unpack and repack this files

Using the links that you gave me, i wrote this algorithm to extract xbb files:
The extracted files have the header PAPA and I developed this code to extract them.
From what I've seen, this is probably a file with information that only the game knows. The extracted files seem to have a pattern, but it depends on the file. If you are interested we can analyze the extracted files.

Oh nice! I will try it!
I need quickbms for this, i guess?

Yea, would be great if you could help me with analyzing the extracted files.
It would be VERY helpful

I used multiex commander to extract the files. May i ask for what purpose do you want to extract the files? Do you want to repack them?

I want to edit and repack them, yes.
And If possible, add NEW FILES to the xbb-files!

Uploaded the Msg.xbb which should contain all Strings etc. Could you make the files "editable"?

btw. I was able to modify some script-related things and to compile it back to the Game! It works!

So the xxb files you can extract with multiex commander. Do you know how to do that?

For the extracted files, i developed a simple program to extract them. Please note that I only take in consideration the Msg.xxb file, wich contains strings. Maybe the PAPA files have a standard format, but I don't have figured it out.

To extract the files, just drag and drop the PAPA file in the executable, or on the command line write 3ds.exe <inputFile>.

Yes, I know how to extract the xbb-files with multiex commander
Did it already and tried your 3ds.exe for decrypting "PlayerAvatarData.xbb/PlayerBodyData/" and got a clean txt!
it seems to work for all the papa-files.

This is really great!

Are you able to make a papa-repacker and xbb-repacker to add new things to the game?
Want to add a new AvatarBody (Character Outfit INgame) to the game. I have to add new lines to the papa-files like this one

PlayerBody
CUSTOM_OUTFIT
b_999

EDIT: For some pp-files, it seems that the 3ds.exe don't decrypt all needed infos.
In AvatarBodyData, it forgets the Object Name

It may work for all PAPA files but some have additional data that isn't considered in extraction.

For instance in FlowerList.xxb/FlowerData extracts (i think):
But it has some more information:
ITEM_RED_ROSE
ITEM_GARBERA

So as I said, I think that it extracts all the information from Msg.xbb PAPA files, but not from others. If you want I can help you, but you have to take a look with me to this files.

I think that yes, I can make the repackers, I will start with the xbb repacker.

Yes, I tried this with AvatarBodyData already and it doesn't extract all the informations.
Sure, tell me what I have to do

So from the image that you posted, there are some script files associated with xbb/papa files? I don't know anything from 3DS file format, so I need the much information that I can get.

If you can post one of the scripts and the corresponding xbb file it would be a great help.

Yes, some Scripts are associated with this files.

I uploaded a example

The Game is written in Squirrel Language with uncompiled scripts (.nut)

Can you post here the AvatarBodyData file?

Could you upload the source, too? want to see how this works :3
