how to set Turbo fire speed?

[jhocking]

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

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.)

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