rsf mii editor permission missing?

[RSChao]

I'm trying to make a program to write to the mii editor and to the SD card, but I cant find a way to save the damn file without my 3ds absolutely crashing. Maybe I need to modify my rsf file?

This is the current rsf code

BasicInfo:

# Specifies the root path of the read only file system to include in the ROM.
# RootPath : $(APP_ROMFS)

TitleInfo:

FreeProductCode : true # Removes limitations on ProductCode
MediaFootPadding : false # If true CCI files are created with padding
