Hello Zitamina!
Actually, Shift-JIS is just a method for writing Japanese on a computer.
If you're interested in installing the ability to view Japanese, so you can play Visual Novels, you will need to set your System Locale to Japanese. ... If you're using Windows 7 or 8, the process can be done via this process: http://aarinfantasy.com/forum/f49/t6...ml#post4219281
Please note, this will not change the language of the computer to Japanese, it will just allow your computer to display Japanese fonts. ^_^ Good luck!
