Retron is the bomb. The controllers it comes with suck but you can use your old ones.

I've made a couple of NES portables in my life time. I would recommend using a Retron NES Clone system. Check out my article here: https://kamselectronics.com/2019/01/22/nes-portable-v2/ . The Retron Clone can be bought here: https://www.amazon.com/Hyperkin-RetroN-Console-Nintendo-Entertainment-System/dp/B000MFHH6I
