RUSH2112I cant speak for the iPad, but it works on my android device. This supports iCade inputs too so as long as Minecraft accepts that you should be good.
RUSH2112This will not work for minecraft on iPad. I are support only. To find lists of iOS games it can play open the App Store on your computer and search icade. Or download the free 8bitdo app and they listed all the supported games in the app.
