3DS Mii Maker - Creating an indented Mii name directly on the console
Was able to get this working last night. This will allow you to hex-edit your Mii name on the fly without the need of a computer. 0A was used as an example here but any supported symbols would work (including normally blocked ones like % and @)
This also means it's possible to get indented names on Wii U without modding the Wii U console.
I used lowercase P (Hex value 70) to mark where the indents would go
