As others can have the same doubt, I thinks that's a good idea.

Right, I think I understood it now. So what about "Japanese, English (unofficial)"?

Well, because officially there isn't an english version, if the game were to be republished, for example through the old game buying channel of the Wii, it will be in japanese more than probably, and if you look for the original cartridge it can be only found in that language, so the game is in that language even thought you can get a translation.

I thought that much, but the real question is why it doesn't say 'English' in the language field in spite of an English version obviously being available.

I played a translated rom, the only way of playing it withouth knowing the language. It's a common thing in emulation, and I other console games I expect to review will probably be of the same kind, as not always the good or interesting games where published broadly.

Why does it list the game language as Japanese when the words on the screenshots are English?
