@paradadf I just manually added your config controller in "RetroPie" line to use combinations: 1.Save\Load = Select+Right\Select+Left select save slot combinations: 2. +- slot =Select+Up\Select+Down it's very simple:)

Good day! The question is: How can I configure a combination of keys on your NES USB gamepad for saving\loading the games and to select and change save slot? At "RetroPie" I just finished writing a piece of code manually in the configuration file, because the NES controller not the default buttons included in the combination to save\load. Here it is possible to do something like that?
