Are the L2/R2 triggers working with jstest from the command line ? Exit EmulationStation, then run
and then test if your buttons/triggers are registering. Interrupt the test with Ctrl+C. If you have more than one gamepad connected, replace js0 with js1 or js2, depending on how many gamepads you have connected.
Both can be hooked up directly, and I prefer the Bluetooth version of the newer controllers due to using USB-C instead of MicroUSB, but I've heard from a few people/sites that the 2.4 are faster with less input lag
However, I've noticed that after updating the BlueTooth controller/adapters 8bitdo sells, they seem to have sped up with my Pi... but I am curious if they really did become more stable, or is there something else.
@melbmatt50 I've only ever used mame with an all-sega image I built a couple months ago and used retroflag's wired megadrive controller, so no analogs but it worked fine, though I never tested the mame stuff out on analog controllers.
Do you have the same problem with other mame cores?
@buzz Which 8bitdo controllers do you use? Are these your primary? I bought and set up a pair of SN30s in January(they seem to be a discontinued version now, maybe for good reason?) for someone and they seemed to be fine for sidescrollers but were finnicky when charging. I want some low profile wireless controllers for travel to replace my ibuffalos but was curious if the Pro line is halfway decent for analog based games like N64 or PSX.
