Please note:

Sekaiju is made in Japan, therefore default GUI language is Japanese. Here shows two way to change to English.

(a) Select "設定(S)" - "言語(Language)" from the menu and select "English" in the language dialog, and restart Sekaiju. If the menu gets character corruption, press [Alt]+[S] and then [Alt]+[L], and you'll open the dialog.

(b) Open "Sekaiju.ini" in your text editor, change "UserInterface=Japanese" to "UserInterface=English", and then save it, and then execute Sekaiju.exe

Older version than Sekaiju 1.0 has been stopped releasing because of rough-around-the-edges, sorry.
