Assigning button combinations / Multiple inputs for one button

[AaronZ101]

A rather niche use case but basically if you're using a controller that lacks as many buttons as the destination console would usually have (for example wanting to use a Sega Saturn-like BT controller on a PS2), having the option to map (hold [X] Button and Dpad Up/Down/Left/Right for right stick inputs for example).

On Steam, you can do this quite easily by making what it calls a "Hold Action Set Layer" which remaps buttons on a controller as a certain button is being held (I set it 200ms+), and then removes the "Layer" when the button is released, while simply "regular pressing" that same button will have its own action. I only used it to remap stuff on the Dpad to not cheese it too much. I know the blueretro has a thing for "Output 1", "Output 2", "Output 3" etc. but not sure how that works or if its just when multiple controllers are synced up?
