That's not the answer at all. That let's you view the Japanese characters, but it doesn't let you enter them, or, if you already have a way to enter Japanese characters (like me, though I forget how I did it), Pokesav HGSS will still save the game, but the Japanese characters will "disappear" from places like your name (and every Pokemon's OT/nickname) unless you use all punctuation besides question marks and exclamation points (as far as I know). It really drives me up a wall.
