OK what is this?
It looks like a regular SMS game to me, but It seems to be a Japanese version. Does such a thing exist? I've looked for others online, I didn't find any SG-1000 carts or Mark III, wasn't the SMS an updated version of one of these?
Anyway it's not listed on the rarity lists besides for in the SG-1000 section. This game has a copyright date of 1986, the game in the database is 1983, but there again I've never seen one so it may not even be the same thing. Can someone enlighten me.
