I have played the famicom one, and i saw in wikipedia there's a sequel! Why is the first one translated and not the sequel?
I really like those games, someone should translate it, there's no doubt! This game is about fishing, I don't know its story, but if you ever payed the GB game (aka Legend of the River King) you'll make an idea on what the game is about.
You can find some screenshots here: http://www.gamefaqs.com/snes/571280-kawa-no-nushi-tsuri-2/images
The game is in hiragana, with kanji characters, which maybe will make this game harder to translate.
Please, if anyone is interested, it would be awesome you decide to translate it. Or, i cand send screenshots and tell me what does it says!
Thanks in advance!
