While installing custom firmware on a 3DS does indeed remove the software-based region lock, it does not account for locale issues. Locale is additional data that a game will often ask the 3DS for that includes the console's current language and software region. As an example:
- The 3DS is a Japanese 3DS set to the Japanese language.
- You attempt to launch an American cartridge.
- The 3DS tells the game that it is a Japanese region console and would like the game to run in Japanese.
- The game, being an English game, does not have Japanese on the cartridge and does not know what to do with this information.
- The game crashes.
In some cases, games may successfully launch with an incorrect locale, but:
- Games may display partially or entirely in the language of the console, rather than the language on the cartridge
- Out-of-region DLC may not work properly
To mitigate this issue, Luma3DS allows you to specify the game's locale to allow the game to work properly. You may also use this feature to launch a game in a specific language without changing the system language (for example, if you want your 3DS user interface in English, but to launch a specific game in French). This page covers the various ways that you can specify a game's locale.
You must enable the Enable game patching
option for locale settings to take effect. To enable it:
- Power off your device
- Press and hold (Select), and while holding (Select), power on your device to enter the Luma3DS configuration menu
- Scroll down to
Enable game patching
and enable it
- If enabled, it will be marked with
(x)
Some games, most notably Tomodachi Life, are known to not launch with basic locale settings because they look not only at region and language, but sub-region within that region (e.g. a territory or state within that country). You can still set the locale of such a game, but you will have to follow the manual locale setting method (that is, create a file called locale.txt
in /luma/titles/<title ID of game>/
), since the automatic locale setters do not account for this.
The syntax of the extended locale setting is <region> <language> <country code> <state numerical ID>
. For example:
- For an American copy of Tomodachi Life, you would want to write the text
USA EN US 01
- For a European copy of Tomodachi Life set to French, you would want to write the text
EUR FR FR 01
