[Feature Request] Enhanced Input Configuration Options

[Mariosonicman91]

Overview

Input configuration is pretty limited right now, it'd be nice to have a few more emulator QoL options. I'm not asking for Dolphin stuff, just the following.

1. Control Stick Mapping. Let us use any button for up, down, left, or right on the left or right joystick, like with keyboard controls.

2. Multiple Inputs on one Map. Allow us to bind A and B to the same input. Like, they both press Y or something. It's niche but is very useful sometimes.

And heck, if you can add a little advanced control window like dolphin, that'd be really cool.

Smaller details

You don't need a menu to implement Mult-Mapping (.2), just hold down the first input and then tap the other inputs you want (eg., want to map A + B to Y? Hold down A and tap B when mapping.)

Nature of request

Nature? Input, I suppose.

Why would this feature be useful?

Input flexibility is important for player-side QoL and more niche controllers, like GameCube controllers.
