Emulator

Game Name?
Wii System Menu (any japanese version)

Game ID?
N/A

What's the problem? Describe what went wrong in few words.
Starting in 4.0-822, installing System Menu WAD of a japanese version (for example, v128 - 2.0J) and then booting System Menu will show only english text and an error page when accessing Settings menu

What did you expect to happen instead?
When booting from japanese Wii Menu, all text should be japanese (regardless of Wii language settings in Dolphin). Also, accessing Settings menu should work like the EUR and USA variants instead of showing error...

What steps will reproduce the problem?
(you must use Dolphin 4.0-822 or newer)

1. Grab a WAD from a japanese version of Wii Menu (either from update partition or from NUS Downloader)
2. Install it in Dolphin through Tools => Install WAD
3. Boot Wii Menu through Tools => Load System Menu
4. Emulation will start. Note the Health and Safety text that will be in english instead of japanese
5. Click the circular Wii button and go to Settings. You'll have an error page instead of the settings

Which versions of Dolphin did you test on?
Dolphin 4.0-2109 [x64]

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Any version of Dolphin before 4.0-822 doesn't show that issue

What are your PC specifications?
CPU: Intel Core i7-3630QM @ 2.4GHz
GPU: nVidia GeForce GT 635M
RAM: 8 GB
OS: Windows 8.1 (Update 1) [x64]

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

• Screenshot of the error page: http://goo.gl/kLS6jt
• From what I tested, Pull Request 48 (https://github.com/dolphin-emu/dolphin/pull/48) caused the regression.
• Accordingly to WiiBrew, this error occur on real Wii if you, for example, install japanese version in a american Wii (soft brick). It may be related to Dolphin selecting the wrong 256-byte settings.txt file when booting Wii Menu.
• This may affect other japanese Wii softwares, but I don't own any to test...
