Cant save controller mapping in retroarch

[Storm]

Hey everyone I need some help. I bought a arcade kit and I am having trouble getting the control mappings to save . When I use MAME or a MAME core in retroarch I have no issues. When I try to map controls using retroarch with the FBA (Final Burn Alpha) Cores loaded to play my Capcom Play System I, II, and III games, they don't keep upon exiting retroarch. I've tried to save core overrides and save game overrides, no luck. I've tried to save current config, no luck. Thanks for any help you can give.

I believe to change controls you have to save a remap file not a config the option to save remaps should be somewhere in the controller settings where you set the controls. I believe you should be able to set remaps just like overrides by core, game and content directory.

Thanks, I will give that a try.
