Simply right-click on any executable file and select the Locale Emulator context menu item, and then one of the available locales to run the executable using that emulated locale. The files that are inside the folder are required, and the program won’t work properly if they are missing.
Note: Move the archive to a permanent location before installation, as you cannot move it afterwards directly anymore. The most important reason is that Japan MapleStory will become 64-bit. However, certain programs might not run properly if not supported by it officially. The project is similar with Locale-Emulator, but LE doesn't support 64-bit application, so I base on Detours to start a new project. It is quite useful when you are trying to play. Add the Japanese language from the given list. To addon,designed specifically for playing computer games that require a specific locale either game or application. Click on the Japanese language and click on Set as Default button. This is mostly used when you are trying to run a application (Galgame, Online game, etc.) which can run only in a specificated region.
In most cases, the executable, which is loaded using LE, will treat your OS as in the new language which is simulated to. That is, to simulate the UI language, timezone, codepage etc.
Locale Emulator provides the same region simulation feature like NELTA and AppLocale. It is a free open source program for Microsoft Windows 7/8/8.1/10 to run programs in a locale other than the default locale of the operating system.
In short, Locale Emulator is another tool for Windows language and region simulation.
