How to change Font size

• Close the game

• Open Windows' Language Settings.

• Under Preferred languages click Add a Language.

• Choose Korean and download it.

• Download the Language Dependencies too.

• You can remove it afterwards if you want.

Observation

The problem behind the small Font is usually related to certain missing Korean fonts, which are usually substituded by other ones in the system, and they are usually too small for roman letters.

If after installing the Korean language, it did not work, you can look in your system for these installed fonts:

• Gulim;
• GulimChe.

If they're not installed, you may go to the installed language, select options and click Download for Language Pack.

You may also install those manually.
