@substring thank you sub! Just what I was looking for

Is there a different manual somewhere? fast forward isn't covered here at all?
https://github.com/recalbox/recalbox-os/wiki/Manual-(EN)

Maybe I missed something, but I recently installed, and input_hold_fast_forward is bound to right d-pad not toggle. I'm just trying to change it to toggle that's all.

I am trying to permanently bind the input_toggle_fast_forward feature to "Hotkey + DPAD right" (or +2 axis in my case)

I can go into the retroarch menu while in any game, and bind it there, and it will work for the duration of that game, however when I exit the game, it reverts back to hold_fast_forward.

I've tried editing /recalbox/share/system/configs/retroarch/input/DEFAULT.cfg but it doesn't seem to have any effect.

How can I make this bind permanent?
