Last update: 01/14/2017 3DS Mii Edit Tool By using this tool you are responsible of any data lost, so please keep a backup of your CFL_DB.dat file. I've been working on this for some time and I think it's ready to be shared. This was made with VisualStudio, so it NEEDS .NET Framework (4) to work. What will this tool let me edit? Name/Author (You can use special characters from DS/DSi/PictoChat/Wii/3DS). Favorite color. Gender. Birthday. Change its "Favorite", "Sharing" and "Allow Copying" properties. Set its specialness (keep in mind that a Mii can't be special and have "sharing" on at the same time as it will crash Mii Maker). What else will it let me do? (glad you ask) Take ownership of any Mii (so you can edit them). Set any Mii as your personal Mii (this will swap any Mii you want with you personal Mii). Delete a Mii (because... why not?). Export Miis from CFL_DB.dat to a file (*.3dsmii). Import Miis from a file (*.3dsmii) to your CFL_DB.dat. Features that will be implemented: A full "Mii Maker" that will let you edit your Mii's appearance (this is already being worked on). Import Miis from .mae/.mii files (Wii Miis). Allow you to create a new Mii. This tools was made to work with a "CFL_DB.dat" file, which can be dumped using JKSM (Shared ExtData > F000000B > Export) and restored with the same tool (Shared ExtData > F000000B > Import), alternatively you can use extdata_dump IMPORTANT: Miis are not saved in real-time, to keep the changes you've made you need to press the "Save changes made to Mii" before selecting another one, and after you've finished editing everything you need to press either "Save CFL_DB.dat as..." or "Save and overwrite...". Miis are know saved in real-time, the only thing you need to do is save the CFL_DB.dat file to keep any change made. I (personally) think the GUI is intuitive enough and the options are self-explanatory, but any question feel free to ask. Oh, and by the way: it supports UTF-16. Will be updated soon, have a nice day.
