So this question got asked earlier by a new user:
It got put on hold because it seemed to be more about development tools than gaming. However in the comments, the user mentioned that he thought it would fit here because it's specific to using his emulator.
In my opinion this is really great question. He obviously put a lot of thought it to it, and it does have an answer.
I'm wondering if there's a way to make this more gaming-specific so we can keep it around? I feel like it might be useful but I don't know much about emulators or inputs or development, etc so I don't think I'm the person to do it. Thoughts? :)
