Yes, Wii U and 3DS download codes are currently working (see below; thanks

)
With that in mind I have one last code to give away - Shantae: Half-Genie Hero on Wii U. I love this series but I got this code from backing their Kickstarter and ended up getting the retail version anyway. I planned on giving this away in the past few days but never got around to it, and when codes were disabled early I figured it had gone to waste. Glad that isn't the case and now it's someone's. All I ask is that you intend to actually play it. First one gets it.
