How do I save a different controller setting for different games on Project 64?

Im using a PS4 controller to play Nintendo 64 games on my computer. The problem is depending on what game I play, I need to switch what buttons the controllers do so it could better suit my gameplay. Some games with the analog stick, up is down and down is up. Some games like Duke Nukem, I need R2 to be the firing button and X to jump. Iwhenever I try to save the controller settings for any one game, it ends up changing it for all of them. How do I fix this? I hate having to reset the buttons every time I change the game.

Hey there guy, there is this great plugin for n64 controlling called Nrage Input plugin. If you go to your settings and try to switch plugins, you might already have it. If you don't, you can download the plugin right here: http://sourceforge.net/projects/nragev20/

When you set your control scheme, you can save it and load a different one as you please! :)
