This month's selection includes the classic NES Joust-alike Balloon Fight and notoriously difficult Japanese import Super Mario Bros. 2: The Lost Levels. The Wii U versions of these games offer additional features not found in their previous Wii Virtual Console releases, adding savestate support and configurable controls.
Digital copies of all featured games can be purchased with Club Nintendo coins, which members earn by registering 3DS, Wii and Wii U software. The Lost Levels is available for 150 Club Nintendo coins, while Balloon Fight can be redeemed for 200 coins. Also up for grabs this month are the 3DS Virtual Console version of Mario's Picross (100 coins) and the 3DSWare tower defense game Starship Defense (150 coins).
[Update: Players report that Club Nintendo is actually offering the Wii version of Super Mario Bros: The Lost Levels, despite what the Rewards page claims. Take note before spending your coins.]
