Nice progress so far guys, keep it up!

How is the effect of a hacked save when returning to the Badge Arcade?
I'd assume a "corrupted file" message or something.
Hopefully when and if a full featured tool is made it can contain a save backup and swap feature with a "haxxors" badge if we find a way to make custom badges, just as a reminder not to hit the game or post on miiverse etc.

Speaking of custom badges, anyone try digging into the badge image data yet?

if the extdata is corrupt then no badges.
corrupt or not, any edits, and the changes will be lost because the badge center will redownload your extdata and you will lose your hacks

How about focusing on the servers?

Thanks for the info.

Well glad they make a server side backup.

Badge disappearing will mean a corrupted save and running the badge arcade again will restore it if ya lose a backup. (I'd rather rely on my own backup but eh)
Good to remember if and when others start asking about that over and over again.

This will be a bit convenient really.
Means we don't have to go nuts about making and restoring backups just to run it again, just lose our hacked state like we do with custom themes when trying to switch using the regular theme changer.

I can't seem to dump the image data myself with the Extdata Dumper for some reason, it just doesn't appear in the folder :/
The only message you get with a corrupted file (or swapped file with someone) is "There are no badges" when you try to open "Place badges" menu.


and now I just paid for this game 2 times and got 10 or 20 badges. completed 2 or 3 collections.
Here is screen shot and some comment by me. Sorry I'm not exactly understand the data. just a sample.
left one is new right one is old.
I think other some hex mean how many badges you have one by one.

EDIT:
I think we need a completed save data. I saved 3 savedata, so if someone need these files feel free to give me reply.

EDIT2
Here is badge count! I confirmed.

Nice progress over here, I'll try Hex Editing it to see if it works!


Would you mind sending it to me as well? I'm working with him(sorta) and that'd be loads of badges to test with! :)

Partners in crime, I see ( ͡° ͜ʖ ͡°)
 
Oops, sorry, didn't refresh! :P It also does this to me if I open home menu in Smash, then go to place badges right away.
I guess that's because you have Old 3DS which has less RAM and that's why you can't place badges when 80MB of RAM (Smash, MH4U) apps are open.
 
Huh, I just uncovered an interesting thing.
These values at 0x358 ascend every time you get the badges. They do it by adding another F at the end (or the beginning since it's little endian) of the string (?).

It's way more complex than I thought, I'm putting the editor onhold for now, I have to uncover every nook and cranny there is.

EDIT: Hype, I am able to add my own badges to the old save file using Hex Editor and the values from the new save. There's a little catch though :P

EDIT: Okay, I fixed it again. Figured out one new thing, adding to that research post.

Hmm, curious.
Wonder how crafty they are with this one.
Thanks for sharing btw.

Sounds kinda scary to see a "no badges" message but glad it doesn't hurt anything.
