L and R buttons not working SNES

[gabgreen]

Hi guys!
I recently got my pie up and running and everything was working great until I started trying to play some games. I was able to set up my SNES controller without any issues but once I booted up Super Mario World I couldn't use my l and r buttons. I've tried to set the l and r buttons as triggers and shoulder buttons but to no avail. I know that the buttons are working because they work on the menus and as hotkeys but for some reason I can't use them on their own in a game. Any tips?
Please let me know if you need more information,

Thanks in advance!

The L/R buttons should not function as hotkeys, if you mapped them correctly in Emulationstation (in the input configuration) as L/R, then they should work in-game. You can open the RetroArch GUI menu to check your buttons by pressing Select + X and checking the Input section.
Please see the read this first page and give more details, especially about the controller and emulator used.

EDIT: According to the manual, the L/R buttons don't function in all areas, so it could be that the buttons are working fine.

When in an action scene, the L and R buttons can be used to scroll the screen forward or backward slightly. [...] This function does NOT work in all areas.
