My wife wants to play Nintendo on our TCL 65s434.

I lack knowledge about the minimum requirements to do so, but I installed an emulator app and some games and tried a cheap USB dongle based controller and a cheap bluetooth controller and both are unusable due to the short but instantaneous delay between button presses and game play.

Is there any way to troubleshoot whether this is due to insufficient specs on the TV (so buy a CC etc), compared to lousy controllers (so get a nice one) versus the emulator app I chose at random (so try others)?

Thanks.
