How to set up controller settings per game

hoeveler

Hello! I posted a ways back about this subject, but I'm ready to re-approach it. I didn't quite understand then and I'm hoping it makes more sense now.
My system is running well - I have a spinner, a rollerball and a joystick (eventually will be 2 joysticks).
What I'd like to do is set up some games like Centipede to use the ball, and others like Tempest to use the spinner. Eventually I want to set up all my games that need special controls to be like this.
I know there are RetroArch Core Options... is that the way this would be accomplished?
I tried doing this before and in the process I messed up some other settings - I've now restored to a solid stable state - so I'd like a surgical tutorial if possible?

Only of the core has input related options there, but generally you can remap the input per-game by using input remapping.

Both configuration section support per-game/per-folder or (for input remapping) per-core configuration, which you can save after you configure the input and you're content with the results.

@mitu Oh nice! Thanks. It seems that the feature, the documentation, or my brain has improved since I last visited the site. :)

@mitu OK... NOW I'm remembering the crux of my issue. I don't think Core Input Remapping will work for what I want. What I need is to make sure Centipede and Marble Madness, for example will be looking at the roller ball. It's not remapping buttons on an existing controller, it's making the game use the right controls, and I think I needed to do that in code instead.

@hoeveler If core input remapping doesn't work, you can either do a configuration override (per-game) or manually add the input configuration in a game dependent configuration file (explained also on the same page).
