Trying to learn japanese (Originally thought I would live over there but now not so much) but its a bit hard to tell what games would help me learn the language while playing and which are doing nothing

What else can i do with a modded 3ds? I already have a custom theme, I free-d myselffrom region locks, I have access to the pretendo servers to play games online again, I can listen to music on my 2ds, im trying to figure out how to stream my 2ds to my pc, but what else?
