What you need:

@froggestspirit has made a better tool for badge editing

Edit: @DaBlackDeath has made a tool for lazy/lambda people

Download

I) Extract Badge Arcade extdata

  • With Savedatafiler: Go to "Ext" and press Y on "000014D1" for export data.
  • With 3ds extdata dump: Choose "dump all extdata to sd card" and wait...
---------------------------------------------------------------------------------------------------

II) Get BadgeData.dat

  • With Savedatafiler: In your sd card, go to filer -> Extdata -> xxxx (backup date) -> 000014D1 -> BadgeData.dat
  • With 3ds extdata dump: In your sd card, go to dumps -> 0014D1 -> BadgeData.dat
-------------------------------------------------------------------------------

III) How to edit Badges Pictures


1) Open BadgeData.dat with HxD and go to the offset 0x318F80

2) Ok now select all byte and stop when you reach "2000" here:

3) Next, copy all selected byte, make a new file, paste and save it.

4) Add this to the new file
Code:
43 4C 49 4D FF FE 14 00 00 00 02 02 28 20 00 00
01 00 00 00 69 6D 61 67 10 00 00 00 28 00 28 00
05 00 00 00 00 20 00 00

And save it.


5) Open Ohana3ds and drag&drop the "new file.bclim" in the soft
- Export the picture, edit (64x64), import, and save it.

6) Open the edited file with HxD, delete these bytes:

7) Select all byte, copy, open BadgeData.dat, go to 0x318F80 (or your bclim offset), right click, past (erase all version).
Now you have edited your badge :)

----------------------------------------------------------------------​
IV) How to edit Badge shade

Look, after the bclim picture you have this:
1447697501-sans-titre.png




It's very simple:
00=Hole
FF=Pixel

Select all byte (like step III 1) but stop when you reach 800
- Replace all FF for have an big badge, or 00 for an invisible badge, for example

To finish:

Credit to me and @szymbar15 for these research.

Useful offset:
0x000000 -> Badges Names
0x035E80 -> Badges Series Names
0x250F80 -> Badges Series Pictures
0x318F80 -> Bdages Pictures
0xCDCF80 -> ??? (No tested yet)

Final Result:

What about people who haven't installed badge arcade at all? (Ex. 9.9 users) How would we acquire a badgedata.dat?
 
So for now only people with access to the badge arcade can use this? Guess I'll pay around with it on my o3DS.
We can maybe use badge in the home menu without the badge center (I can use my badges after I have deleted this apps)
But without savedatafiler, I don't know if a tool can dump this extdata.
 
Thanks for the tutorial. I'm having some trouble with the badges showing on the home menu icons, but it shows up fine on the hover over preview. Here is a screenshot of what I'm talking about. I used the Japanese Badge Center until US release, and moved over to US. I found the ExtData in the Eu folder though, and did not see the US folder. Any ideas on what's going on?
 
is there a anyway to make a custom badge open a title ? (ex:a custom badge who can opens irofall)

Thanks! Seems easy enough given you'd know enough hex-editing stuff. Sounds like something I'll mess with later today!

Though... a GUI tool that makes the badge shape for you from a 64x64 PNG would be neat. It could scan whether it's a hole (transparent pixel in image) or a pixel (anything that's not transparent) and output in the hex needed to paste in the badge file.

is there a nyway to make a custom badge open a title ? (ex:a custom badge who can opens irofall)
Potentially, yes, but the main issue with that is that the badges that open titles only open system titles. So no Ironfall, no other games.

I get the following error when trying to dump my EXTdata using EXTdata_Dump.

AM_GetTitleCount() failed: 0xd8e007f7
