Thanks. I'm looking on Amazon. Are these the ones? amazon.com/Logitech-940-000117-Gamepad-F710/dp/B0041RR0TW/ref=sr_1_2?keywords=Logitech+F710+usb+controller&qid=1579098774&sr=8-2
With the INNEXT there are just buttons? Do you use those instead of a joystick. I basically stopped being a gamer after my C64 and Intellivision, so I have zero Nintendo/Sega gaming experience. Thus I liked the old fashioned joystick. And the Logitech is a bit pricey.
If you can step up to $40, this one is fantastic. Fantastic battery life too.
Oops mb linked the wrong one meant the F710
In general your highest quality controllers are 1st party controllers from a modern console. Personally I am a fan of XBox One S controllers (only the newer xbone controllers use bluetooth), but PS4 controllers are quite popular here as is the switch pro controller (which has the advantage of button labels matching Retropie's default). The WiiU Pro controller is quite popular as well as it battery life is second to none, and the build quality is good. if you dont have any of these controllers already lying around than your next best bet is to go back 1 console generation. Xbox 360 controllers work well (you need to use a special dongle, they don't have bluetooth) ans PS3 controllers are good as well.
If you don't have those the 'tier 2' controllers are anything from 8bitdo, their SN30Pro+ is comfortable but I am not a huge fan of their Dpad (some people love them others don't, its not a poorly built product just personal preference). Another controller I would consider tier 2 is the logitech F710 or F310 (Wired and wireless respectively) they are ugly as fuck but the build quality is really good for the price. The third controller I would consider to be tier 2 is the PSone controllers included with the Playstation CLassic, the biggest drawback is that they cont have analog sticks so they don't work for newer systems (they were a good deal when PS classics were selling for less than $20 but for some reason prices have really shot up recently)
There are also tons of cheap controllers on amazon that look just like the original controllers for any retro console. 99% of these are really low quality and I can't recommend them as even though some are good, the quality is very inconsistent. if you need a controller with the exact same feel as a real retro controller you should look into the official Nintendo switch Online controllers for NES/SNES, the only official way to buy them is with a nintendo switch online membership, but the quality is excellent.
Both work very well with the Shield. I've been using the F710 as a second controller for multiplayer emulation.
I like those Logitech controllers. The F310 is a wired USB controller, about $17. The F710 is wireless (over an included USB dongle - not Bluetooth) and powered by some AA batteries. It's also larger and suppers forced feedback (rumble).
You've got two joysticks, L1 through L3 (one button, one trigger, and the joysticks push in), A, B, X, Y face buttons. The only system that this wouldn't have the buttons for is N64, but you can put the Z button on one of the triggers and if you feel comfortable putting the X buttons on the right joystick.
My controllers are these: Logitech Gamepad F710 https://www.amazon.com/dp/B0041RR0TW/. I don’t see anything in the description about unifying receiver.
TBH, I only plug these in when I’m gaming. I can easily pull them out and put them in the little holders I added in the print if I need to plug something else in. :)
