yw_save - Yo-kai Watch save data decrypter / encrypter
...and save editors (see below)


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

After editing, re-encrypt game1.yw with following command:
Code:
python3 ./yw_save.py --game yw --encrypt game1_decrypted.yw game1_encrypted.yw

Rename it and inject it with svdt.
Code:
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 Ganso / Honke
  • Yo-kai Watch 2 Shin'uchi
  • Yo-kai Watch Busters and Getto-gumi
  • Yo-kai Watch 3
You can specify the game with "--game" option.
  • --game yw (default) : Yo-kai Watch 1
  • --game yw2 : Yo-kai Watch 2 Ganso / Honke 1.X and Shin'uchi
  • --game yw2x : Yo-kai Watch 2 Ganso / Honke 2.X
  • --game ywb : Yo-kai Watch Busters
  • --game ywb_getto : Yo-kai Watch Busters Getto-gumi
  • --game yw3 : Yo-kai Watch 3
(for details see https://github.com/togenyan/yw_save/blob/master/README.md )

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


Save editors

I eventually made simple save editors.
These save editors do decryption and encryption when needed (you don't have to use yw_save).

Yo-kai Watch:
https://github.com/togenyan/Yo-kai_Editor_1/releases

Yo-kai Watch 2 (Ganso, Honke, and Shin'uchi):
https://github.com/togenyan/Yo-kai_Editor_2/releases

Yo-kai Watch Busters:
https://github.com/togenyan/Yo-kai_Editor_Getto/releases

Yo-kai Watch 3:
https://github.com/togenyan/Yo-kai_Editor_3/releases

Note: You have to install Visual C++ 2013 redistributable package to run these editors.
https://www.microsoft.com/en-us/download/details.aspx?id=40784
choose vcredist_x86.exe.

Error Reporting
If you encounter an error, please check following before reporting:
  1. You are using the correct version of save editor
  2. (YW2 and above only) "head.yw" file exists in the same directory as "game*.yw" file
If the error persists, please send me your save data files (game*.yw AND head.yw) via PM, email, or GitHub issues. Or you can also post it to this thread directly. In any case, do not forget to write the version and region of your game. example: Yo-kai Watch 2 Shin'uchi v1.2 JP

Error codes
1XX IO Error
103 "head.yw" not found​
2XX Decryption error
201 AES CCM decryption failed
202 Decryption failed​
3XX Encryption error
4XX Save data parsing error
Can anyone help me I don't know anything about coding so could anyone help me with a tutorial or something please help!!!!!!

Thank you for the offer, but I have already added the EUR texts (https://github.com/togenyan/Yo-kai_Editor_2/commit/de2d2cda)

You don't have to use both of yw_save and Yo-kai Editor 3. Just use Yo-kai Editor 3 and forget about encryption. The app will automatically do that.

You need Python 3.x (not Python 2.x) to run yw_save.

Does anybody know whether it would be possible to randomize a Yo-kai watch game similar to how pokemon is randomized? All these event yokai in 3 are impossible to obtain legitimately without cheating so it'd be neat if it were viable to just randomize & obtain them more 'legitimately'

You can't get Dark Kyubi or Illuminoct in Bony/Fleshy because they're not in the game's code (I think) they're only obtaniable on Psychic Specters.

When the new update to BS and FS come, it's possible to get Dark Kyubi. But I'd just play PS, since they come out at the same time.

  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it
    +1
  • DinohScene @ DinohScene:
    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying

    Samsung SD format can sometimes fix them too

    yes looks like an faulty sd

    @Psionic Roshambo i may try that with my dead sd cards
