[Feature Request] Add a simple way to enable original controller keybinds

[HugeTaffer]

As an original 1,1 control scheme enjoyer, I'm pretty sad at how difficult it is to set the port to the original control scheme. I'd like to enjoy all the benefits the port offers with my clunky but really rewarding control scheme. Would be great for preservation's sake too!

And thanks for all the work on this port, it truly is something incredible.
