I'll get right to it, thanks to AllZ0ku for making this working tutorial of how to make a qr code out of a special mii! WHAT YOU NEED: HxD (hex editor) JKSM (3ds app) Mii Edit Tool http://gbatemp.net/threads/release-3ds-mii-edit-tool-edit-your-miis-right-on-your-pc.456607/ (this is optional, but it is useful) cipherMii (Homebrew app) https://github.com/Goombi/cipherMii/releases/download/v0.1-alpha/cipherMii.zip And lastly, this website https://3ds.goombi.fr/editMii/# Step 1: Go to JKSM, Shared Extdata and extract F000000B Step 2: You should have extracted CFL_DB.dat. Put SD card into computer and open this file with HxD. -IMPORTANT- Personal miis cannot be converted to qr code. If you want to convert your personal mii, do this: Open CFL_DB.dat in Mii Edit Tool, go to the all miis tab, click on the FIRST MII IN THE LIST and swap it with the personal mii. Overwrite data and save (make a backup just in case) Continue with normal steps. Step 3: In HxD, delete the personal mii by deleting the first 6 lines, right up to "03". Do not delete 03 or anything after that. Step 4: When the original lines are deleted, select the first 6 lines again but this time copy it. Close the table, do not save (top left icon>close>click no) and then press CTRL + N for a new table. Step 5: You should now have a blank hex table with special mii data on your clipboard. Paste the data you just copied from the last step into this table, and then click the Save button. Save it as "input.mii" Step 6: Copy the input.mii file you just created and paste it into the cipherMii app folder (which you should have put in sd:/3ds/) and put the SD back into your console. Step 7: Open Homebrew, open cipherMii, press B to convert your input.mii to output.bin. Press Start to exit and put SD card back into pc. Step 8 (final!): Open https://3ds.goombi.fr/editMii/# and IMPORT the output.bin file (nothing will happen, this is normal) then EXPORT the QR Code. You have successfully created your own special mii qr code! NOTE: You may have noticed that you can only edit the first non-personal mii you have. There's an easy way to fix this with Mii Edit Tool! Open CFL_DB.dat and in All Miis, any mii that you want to edit that isn't first in the list, set that mii as your personal mii. Then go to the first All Miis mii and set THAT as personal. You just swapped a mii down the list to the top of the list with this simple trick! Extra note: Do not restore the CFL_DB.dat! I am not responsible for corrupt mii data! MAIN THANKS GOES TO GOOMBI, this guide wouldn't be possible without his work. One more thing, this is my first thread or guide that I have made, sorry if it is badly made!
