SAGA PLANETS, a studio under Visual Arts (which owns various brands such as Key,Spray, etc.) has added a system check to thier latest release (Natsu Yume Nagisa) that verifies the user is running the Japanese version of Microsoft Windows. If the user is running a copy of Windows from outside Japan this warning will appear:
This Game is Japan Only
This game is only possible to be played within Japan.
For it to work, you need “Japanese Version Windows”.
The game will now close.
While it is common for non-Unicode program handling to need to be set to Japanese in order for a game to run, this is a technical limitation of the games and is easily fixed by changing the settings or using AppLocale. Some games have also required certain system settings such as date & time regional format to be “Japanese” for the game to run properly but these did not require a particular version of Windows to be purchased.
