Hacking Editing Wii Savedata

pomu47 · Oct 29, 2015

Hello, I am interested in seeing how to edit a Wii savedata
From my understanding, the best method is through Xyzzy, but I can't find a working download link to Xyzzy, is FE100 (http://wiibrew.org/wiki/FE100) the best method to do this? If so, can anybody help me?

Well have you extracted your save data with this? http://wiibrew.org/wiki/SaveGame_Manager_GX
A ton of the wiibrew has been missing for a while. Luckily there are still places to get the needed stuff.
I have over 100TB of storage loaded with most of the wii tools and other stuff. I can look to see if I still have fe100.
But there are other things that work too. http://sksapps.com/index.php?page=wii/wiidocs/Wii_Savegame_Parser.html
http://git.infradead.org/users/segher/wii.git
negentig -- decode and unpack a disc image
* tachtig -- decode and unpack a saved data wad (data.bin)
* zeventig -- decode and unpack an installer wad
* twintig -- pack and encode a saved data wad
* zestig -- decode and unpack Wii flash images
Some stuff still remains on wii brew though.
http://git.infradead.org/?p=users/segher/wii.git;a=blob;f=tachtig.c
There was a post here on gba a little while ago about savegames.

If you need any help I would be glad to assist. If you don't mind me asking what are you editing?
Edit: found it this is fe100 I knew I had it stored somewhere. Enjoy.

Yeah, I have extracted my save data using SGM GX, but I don't know the next step, I've downloaded FE100 already but I can't seem to use it completely without having the homebrew app "Xyzzy"

Here how you will use the FE100KeyGrabber,

1. Click the ‘Get stuff from Interwebz’ button to obtain sd-key, sd-iv
and md5-blanker
2. Get a savefile from your wii (no matter what) and click the ‘Get
stuff from a savefile’ button and point it to the savefile…

It will give you
Ng-id (your console’s id)
NG-key-id
NG-mac (your console’s wifi adapter’s mac address)
Ng-sig (your console’s elliptical curve crypt. public key)

and finally,

3. Click the ‘Get stuff from xyzzy key dump’ button, there you should
provide your keys.txt you obtained from xyzzy tool by bushing… This
step will extract the ecc key (NG-priv) out of keys.txt and you will be complete...

I have the save data extracted from my Wii, but when I follow the first step, it doesn't connect for me, I left it for about 10 minutes but it didn't finish connecting to obtain sd-key, sd-iv and md5-blanker.

Do you by any chance have Xyzzy? That was the main thing I've been looking for since I can't seem to find a working download link anywhere.

I also don't know how to use segher's program, as I have no previous knowledge on this subject whatsoever.

Edit: I'll read his guide, thanks for all the help!

Indeed I do.

But if I remember there is a more up to date way of doing this. Just can't seem to remember though.

Can you pm me the decryption key? Thanks for all your help!

No, you don't need the "decryption key" . I am just an idiot sometimes and uploaded the link that needs one. Sorry.
This one shouldn't need a key.
Lol, Had to edit the link cause I still didn't get the key attached...lol.
Sorry, it's a link that isn't really coming from mega.co so I was having some trouble linking it. It's up now. Sorry.
Lol, plenty more links to go around.

Do you have skype or a method I can contact you for help by any chance? If not I'll just ask questions through this thread.

FaTaL_ErRoR · Nov 13, 2015

Sorry, no skype, no facebook, no twitter, no direct line of communication. I log in here using an IP that does not belong to me. (I am a very paranoid person) There is not one place that my IRL and VL (virtual life) intersect. All information about the area I live in that I have posted in other forums is complete lie. Even my gamer tag I have given out on many different sites for different consoles isn't my gamer tag. (That is how paranoid I actually am)
You will have to post in this thread or via pm and I will answer to the best of my ability. That also allows other very smart tempers to post as well.

pomu47 · Nov 19, 2015

I understand, don't worry.

First question: How do I run xyzzy? I don't think it's a homebrew app, so I'm confused how to start it.

FaTaL_ErRoR · Nov 19, 2015

Here is a great starting point for you. https://gbatemp.net/threads/wii-key-grabber.96750/
It goes in your sd card just like any other app. just change xyzzy.dol to boot.dol.

This is also a great tool.

You can unpack the data.bin using SaveGame Manager GX once it's on your USB/SD Card.

That makes it easier because you won't need to use FE100.

Also, some games use a CRC check, so to calculate the CRC when you modified your data you need to cut off bytes with a hex editor, then you use a tool to do so. Before modifying the data, I'd check for it and try seeing if it matches the CRC stored.

The CRC is four bytes and either at the start or the end of the data.

This is important because if you modify your save data and don't change the CRC, it might say your data is corrupted.

When I run Xyzzy (after changing it to boot.dol) in HBC I get the following error:

Where can I unpack the save data in SaveGame Manager GX? I haven't found the option to do so (once it's on my SD card), do you mean extracting it first via SaveGame? Or moving it from the wii data menu -> my SD card?
Edit: If you mean by extracting the save data to my SD card I've already done that, but I don't know what the next step would be (for reference, I'm looking to edit a Mario Kart Wii save data)

Larsenv · Nov 24, 2015

If you've extracted the save file with SaveGame Manager GX, you will have it already extracted in the subfolder of the savegames folder. Now you don't need WiiSCU or FE100, and this is easier.

By the way, since you want to edit the Mario Kart Wii save file, you can unlock everything with a cheat code. (if you use a usb loader, you can download the cheatcode with that name.)

pomu47 · Nov 24, 2015

I'm looking to edit a specific value that is already existing in the save data (but yes I know I can unlock it via a code) into a different set of numbers.
Edit: Once it's on my SD card, what should I do next?

I've looked back on this thread since I've gained interest in this again. I've used savegame manager GX to extract my save data, how would I go about unpacking it? When I looked that up I got a thread from 2008, could you point me in the right direction? Please and thank you.
Edit: If it's easier for you, I can contact you in PM sometime and I can discuss what I'm trying to do with you so it would be easier to help me.
Edit2: I figured some of it out more or less, but someone with more expertise would be extremely useful, is there any way for me to contact you off site Larsenv?

Yes, I have some other ways that you can contact me...

Sent you a PM with the information.

I am hoping you can help me. I have not seen you use this forum in quite some time, but maybe, just maybe you will see this.

Of course I am open to anyone helping me.

Here is some background: I Love "My life as a king". Like really treasure it. I purchased most of the DLC for, and there lies the problem, I really want ALL the DLC. I have a Save File with most of the add on content, but I dont have some key pieces, most notably the "Infinity Spire" DLC.

Here is what I am looking for: Can someone help me edit my save to include ALL add-on content.

Any help would be amazing!

DLC is installed on Wii, it's not contained within the save files. That is, if you have an edited save with DLC items added, but the Wii you're running that save on does not have the corresponding DLC installed, it won't work.

You want to use a wad manager (like mmm) to install the DLC wad (which we can't link you to).
