    I figured out how to set a turbo button thanks to this old thread: https://retropie.org.uk/forum/topic/15185/did-the-turbo-button-function-exists-if-so-how-can-i-enable-it

    However I'm wondering, is there a way to set the rate of turbo firing?

    In many games the turbo fire results in bursts of bullets instead of a steady stream, and I'm guessing that's because the default turbo firing rate is too fast for the game to handle. In that case, reducing the rate a bit would be beneficial.

      # Describes the period and how long of that period a turbo-enabled button should behave.
      # Numbers are described in frames.
      # input_turbo_period = 6
      # input_turbo_duty_cycle = 3

      In many games the turbo fire results in bursts of bullets instead of a steady stream, and I'm guessing that's because the default turbo firing rate is too fast for the game to handle.

      Or it could just be that many games limit you to for ex. 3-4 shots on-screen at one time. Try shooting like tap........tap-tap and then hold down turbo; if your shots repeat in the same staggered pattern, it's because a new bullet is fired each time an old one moves off the screen. In regular play it will look like bursts because you shoot 1-2-3 and then can't shoot any more until the first one's off-screen, then you can shoot 1-2-3 again as they scroll off one after another.

        @sleve_mcdichael Thanks! And can that be modified from the RetroArch gui just like setting the turbo button, or do I need to edit the config file text?

        EDIT: I figured out that I can edit that setting in text by plugging in a keyboard and then go to RetroPie > Configuration Editor > Advanced Configuration > Manually edit RetroArch configurations > all/retroarch.cfg

        Increasing the period to 9 seems to work better for the games I tried (eg. 1942, Twin Cobras, etc.)

        and for future reference https://retropie.org.uk/docs/Configuration-Editor/

          The settings are accessible only when Show Advanced Options is enabled (menu_show_advanced_settings = "true"), they're found under Input -> Turbo Fire.
