Deadboy Wrote: Vouch on these. Best free emulators you'll find. The premium/paid version doesn't offer anything too fancy either, so you're not missing out by being a free user. They also have controller support, which is fantastic because I like to play with my bluetoothgamepad. Get rid of all the buttons on screen, turn on the controller and play away.
Yep! I have it both on my tablets and my phone, and I specifically got a phone case with a stand so I can just set it on a table and kick back comfortably. I recommend using an 8bitdo SN30 Pro because of its form factor and amount of buttons, but if you don't wanna carry that around you can always get an 8bitdo Zero and keep that in your pocket.
