OK, I think I’ve finally got my two controllers working properly, and I know, in general, how to configure them in all three places I need to — MAME, Retroarch, and Emulation Station.

Now, it occurs to me that these configuration files are fine if you plan to keep the same controller or two plugged in all the time — but what if you want to switch out controllers? Let’s say I wanted to use a Nintendo-like controller for NES games, but a PS1-style controller for PSX games, or maybe my girlfriend wants to bring over her own… you see what I’m getting at. Is there a way to maintain a “library” of controller configurations and swap between them? (I imagine a shell script could do most of the work; I’m just wondering if there’s a built-in solution.)
