One of the countries where it was released was Spain. Magazines reviewed games, though strangely, in its original japanese versions, and sometimes, they mentioned games like Final Match Tennis and Operation Wolf needed adapter (were they released as such?).
Anyways, I bought one cheap a few years ago and is the one I use to play. What intrigues me is that the system didn't have RF antenna, and not much TVs had AV back in the early 90's.
