If you go just above the $200 price point, Retroid will release a new handheld in January that can handle everything an AYN Odin 2 can. Well worth the asking price of that. For less than $100, you have the Magmi Air which might work for you. A 3rd option would be, Magmi will release their second handheld, a Magmi Pocket. That will likely be under $200, and will likely handle NGC just fine.
How come I don’t see IronFox mentioned lately? Was there some news I missed?
