From Wikipedia:
Mario's Super Picross (マリオのスーパーピクロス Mario no Sūpā Pikurosu) is a Super Famicom sequel to Mario's Picross. It is erroneously named as Mario's Picross 2, which is actually the name of the Game Boy sequel to Mario's Picross. The game is compatible with the Super Famicom Mouse.
After the failure of Mario's Picross in North America, Nintendo decided not to release this game in that region and instead only in Japan. It was later re-released for download on the Wii's Virtual Console service on December 19, 2006 in Japan. In PAL territories it was released on September 14, 2007, the 12th anniversary of the game's original Japanese release, marking the first Western release of the game. It carries a price of 900 Wii Points, 100 more than a normal Super Famicom/SNES game. The Western Virtual Console release has been left nontranslated, with original Japanese text intact.
