IF YOU USE RETURN TO OPTION THEN THE UNEO TITLE MUST BE ON EMU NAND AS WELL FOR PARTIAL AND FULL EMULATION. *Added back our old font as fallback font in case the wii system font can't be loaded. Also the use of the Wii System Font can be disabled in the settings (don't forget to set font scale back to 1.0 for old font)
