A friend of mine pointed me in the direction of a .gba for the Japanese version of Hikaru no Go! I tried it out on my normal gameboy emulator and it works great.
If I persist, it'll be the first Japanese game I'm attempting to play in Japanese. I had tried going through the story mode in Guilty Gears X a few years before, but, alas, it was too hard.
All in all, it's looks a bit harder than pokemon (which I hear only use kana, and would be keen to try too), but not impossible. I started out by making a list of really common words/terms in igo, and expanding on it while I play (adding things that come up again and again).
囲碁 いご igo
碁石 ごいし go stone
碁盤 ごばん go board
碁笥 こけ go bowel

I can't select the text on the screen, so for kanji I don't know I'm looking them up using jisho.org's kanji by radical.
