[neko00]

Thank you a lot for the help! It finally worked. I will also give a try to the busters' editor now! I wish I knew how to make a save editor, but I am a total noob...sorry orz Thank you very much again!

Make sure you have backup before injecting new save data.

What does it mean the #1, #2 and the two quantity fields in the editor?
How do I use them? I didn't saw any documentation in the readme file.
Thank you

I would also like to know this.

I keep getting error 202 in Windows 7 when trying to import game1.yw. Help? Tried decrypting it with your script, but that shits out "Unable to create process yada yada". I have both py2 and py3.5 installed.

Actually I don't know what those values mean. All fields' name are just my guesses.

Error 202 means the app failed to decrypt your save data.
I'll look into your problem. Could you send me all of your save data files? Also, please include the following information:

1. The title and region of the game
2. The tool you used to dump your save data

Is there a way to create bat files or executable .py files for this?

I'm looking to streamline the process for those less code savvy

That way, people don't have to install python and can just en/decrypt files.

you can convert/port/etc python files to .exe files, with some tool... i forget the name. either i google it or you

Awesome work guys..

Now to find out how to make these tools work..... I'm a c++ kid. never dabbled with python before lol

I do not remember the steps I took to to go from .py > single .exe but this release of mine shows a final product of what you can get

if you actually know c++ python will be so comfortable, i don't like programming in c++ anymore

yw_save - Yo-kai Watch save data decrypter / encrypter

https://github.com/togenyan/yw_save

This script decrypts and encrypts save data of Yo-kai Watch.

• You need Python 3.x to run this script.
• You need PyCrypto to handle saves of Yo-kai Watch 2 and Busters.

Currently injecting doesn't work on Yo-kai Watch Busters.
(2016-03-18T19:11:06+09:00) Yo-kai Watch Busters savadata encrypting is now supported!

Usage

First dump game1.yw (the number depends on your save slot) with svdt.

Decrypt game1.yw with following command:

python3 ./yw_save.py --game yw --decrypt game1.yw game1_decrypted.yw

After editing, re-encrypt game1.yw with following command:

python3 ./yw_save.py --game yw --encrypt game1_decrypted.yw game1_encrypted.yw

Rename it and inject it with svdt.

mv game1.yw game1.yw.bak
mv game1_encrypted.yw game1.yw

Decrypting, encrypting and injecting works with:

• Yo-kai Watch (tested only on JP version, but it should work on other versions)
• Yo-kai Watch 2 Shin'uchi
• Yo-kai Watch Busters and Getto-gumi

You can specify the game with "--game" option.

• --game yw (default) : Yo-kai Watch 1
• --game yw2 : Yo-kai Watch 2 Shin'uchi
• --game ywb : Yo-kai Watch Busters
• --game ywb_getto : Yo-kai Watch Busters Getto-gumi

I hope someone will make easy-to-use save editor...


Save editors

I eventually made simple save editors.

Do you have a plan to compatible with yokai sangokushi checksum calculatuon? I'm searching how the game calculate but no idea.

only I know, 0x00 is the sum.

 

[dope92]

Well I'm officially lost. My code know how is useless due to how old I am to all this.

Can't build this or pip the installer.

Currently, I have no plan to support Yo-kai Sangokushi, sorry.
For your information, so far, Yo-kai Watch games use CRC32 to check validity of encrypted save data. But it seems the internal system of Sangokushi is much different from previous games as it is not developed by LEVEL-5.

Thanks for the Yo-kai Editor Getto.

One quick question though. I downloaded the executable for windows 7 and the entire program is in Japanese. I noticed it has a translation folder but I cannot find any way to translate the program.

Is their a way to translate it?

Files under the /translation are Qt library thing. They are not for my app. Currently no translations are available.

I added translation support, but no actual translations are made yet.
For translation details, see

[SoyAlexPop]

I can't make this work in mac or windows, QT is being a total pain in the ass and I can't download the 5.5 files.

So if someone can edit my save file, it would help me put the game to rest till we get the gem cats coins.

I need
Anglerfish (Rare) x2
Rhino Beetle (Rare) x3
Dorcus Stag (Rare) x2
Marlin (Rare) x3
Purple Coins x15

And if it's possible Pandanoko only if it can be added to the medallium if not, please don't add him.

If any of you can do it, thank you.
