Translation by a new language
The languages which can be used in OLB are English and Japanese, but it's possible to translate by a new language. A procedure of translation using "Loco translate" plug-in and "Poedit" is written in the following page.
And, some translation files are published in this page. Those files were given by kindly users.
I am grateful to them very much. Thanks.
