Hi, I would like to bind a turbo button in retroarch's general input menu to work with any core. Currently, I have make this work just fine, but the thing is that any time I exit retroarch it goes back to nothing, the settings wont save at all. I believe this is caused by batocera or emulationstation overwriting the input information every time I start a game. I have confirmed this by looking at the retroarch conf file located inside the user folder. Changing that manually does nothing because, as I said just before it gets overwritten when you start a new game.
I know there are cores that support Turbo functionality, but I was just looking for a fix that could apply to all of em.
