Games in Japanese

[HiddenAce]

How can I play games in japanese?
do I have to get the Japanese versions or is there an option for this?
I tried changing the language but that only changed the menu items

Changing the language in Dolphin only affects all of the text within Dolphin, not the game. To play games in Japanese, the game must have the option of using Japanese text and/or audio. Most NTSC-U and PAL games do not have this option. The only way you can do this, a vast majority of the time, is to play an NTSC-J game. Often, you'll have to import the game from Japan, then dump the disc so it will play in Dolphin.
