Most likely if you had a platnuam account on Club Nintendo before July, you recently got an e-mail about your reward. You had two options A: a Mario hat or B: a Punch-Out!! Wii Ware game. The Punch-Out!! Wii Ware game is Little Mac Verus Doc Louis. On november 1st the will send every one picked this reward an e-mail with download code for the Wii Shop Channel. This not a Wii Ware game or DLC it's just a Club Nintendo offer that you can only get via download code. Well it may be to late for some you who don't have Club Nintendo accounts but this is why you should have a Club Nintendo account.
