I have an iPad 2 (not air) that I want use strictly with an iCade. I don't think they even make the boxed iCade anymore, not for years. It's a brilliant bit of kit, however mid revisions of iOS 9 broke the ability for it to connect through bluetooth as has every iOS version since. I just need to downgrade to get it to connect and then I don't plan to connect it to the internet ever again. Just a nice bar top retro game machine. So is this kind of downgrade even possible?
