R4 Languages?

Alright so, I just got the R4DS, a few days ago.
I understand how to put games on it, and music and everything.
But I downloaded a Japanese game, and i can't quite understand it.. If I try to teach myself to read Japanese I'd probably fail epically. :(
So, I was wondering. Can you change the language of a game, on the R4?
Somehow..?

No... You can just download an english version of the game... Or a translated one (if it exists)

Most of the Japanese roms are translated into English (like prof. Layton :D)
