NES emulator compatible with iOS 9, iPad

Good morning, I'd like to tell you that I have an iPad (iOS 9) mini with an iPEGA 9023 controller working perfectly with an Snes emulator.
Well, my dream is not yet complete since I haven't been able to find a NES (NINTENDO) emulator that works with the controller and with IOS 9.
Believe me, it's not laziness to write here and wait for a solution, since I've searched even at the bottom of Google and can't find anything. I would really appreciate it if someone had any good information.
A true Nintendo lover says goodbye, hahahaha

Thank you.
