you know, Korea doesn't use english alphabet. They(or we because I'm Korean) use 'hangeul(??)', or Korean character.
And, everyone think korean powdertoy is impossible because hangeul has over 10000 characters.
But, in powdertoy cafe(it's not place where people just drinking coffee. It's online community.)they did it.

Yes it's Korean site so maybe you cannot read it, and because of you didn't logged in you even cannot download it.
So I uploaded it in dropbox.

It is not work by me. I don't even know how they did it. But the importence is you can translate powdertoy in another language even if it's not using alphabet.
I think 'Korean Translation Mod' is better name
