Re-Mapping a Controller

I'm a total Noob to RetroBat so be gentle. I have a generic USB N64 Controller and I mapped it incorrectly in RB. How do I re-map it so I can use the menu's correctly? I messes with my in-game play as well because I have the A button set up to go to the RetroArch menu. I have re-mapped it within RetroArch but it doesn't seem to work still. Help please! Running the current version of RetroBat

Have you tried reconfiguring the controller in the ES menu?

If you are playing 64 games I would use a menu combo like down and start to bring up the menu rather than a native button. On my 8bitdos with extra buttons I use one as a modifier.

ES and RA are different though RA should technically autoconfigure from ES. You can turn this off in ES.

You could also create a mapping and save it as a core override so the system is mapped how you want.

Just spitballing here.

Have you try with the start menu, and use the "controller settings" function ?

I’ve gone to the controller settings in RB but when I press A to map it, it goes back to the previous screen. I also have a PS3 controller and it lets me re-map no problem. The controller functions fine when I plug it into my laptop and use OpenEMU
