ROM Hack [Release] Yo-kai Watch save data decrypter / encrypter

[Glyptofane]

Can I get the bells for Sailornyan/Robonyan F with this?

Yes, but they don't work. When you go to fight them, they tell you that you don't have permission.

Is there any way to input passwords into your savefile with this? Would be great if you could put a buncha passwords in a text file, feed it to this program and then have it unlock the rewards and use up the codes. It's so tedious to input those codes.

 

[Skylinedeadline]

Does anyone know of a way to add spotpass/streetpass hits? Like is there any way to make pandanoko appear in the hotel room without actually getting 10 spotpasses from another 3ds? either through hex editing or the save editor? Obviously one can just plop him into their inventory, but I'd rather actually fight him if it's even a possible thing to modify.

So I added some items to my YW2 file. And I got "unable to recognize save data". Now not even my backup saves are recognized. Any help?

Attached my last backup.

use savedatafiler to delete the secure value

 

[xelestial]

why can't edit Attitude and Loaf by YW2 save edit

 

[DesperadoV3]

What does auto numbering, update index, fix ID, and fix IV do?

 

[MariahKat]

Stupid question, but how the heck do you dump/extract/whatever the save? I've dumped many games before so I know how, but yokai watch 1 and 2 just make it hang up and freeze on red screens no matter what I try...I have download versions, is this an issue???

 

[DesperadoV3]

Is there any way to update the medallium with manually edited Yokais with Yokai Watch 2 Editor??

I inserted a Pandaneko but the medallium doesn't recognize it.

If you have another 3ds and another game, you can touch trade the medal and it'll register into the medallium

 

[Deadshot626]

On the Yokai Watch 2 Editor what are IVs and EVs and Sports Club? Can someone explain to me what these do.

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.

Curre

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 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...

i am surprised this editor doesn't go up past 429 yet. (aka does not have moximus M and moximus F and above but the key items are in the game files for these yokai and such.) but then again i shouldn't be surprised as the games don't list past 429 yet..(once the update to yw2 happens, it will add 430 and up.)

 

[kumarachristian]

im using the medal cheat but it doesnt get registered into my medallium,guess the medal cheat isnt ready yet

[chinesekidx]

does anyone know if there's a way to switch the save file orders? or delete save files in general maybe through hex editting or something? specifically in yw1

 

[VoidDeviant]

Has anyone figured out how to activate the event flag for Sailornyan & Robonyan F? You can add the bells, but it says you don't have permission. Is it possible to get a way around this?

We need to activate the flag that let's the game know we got them through the bank.
