@markyh444 First, let me apologize if I came off as needy or rude. I was having trouble locating the information I wanted, or had trouble understanding it I guess would be a better way of putting it.
Secondly, I would like to thank you for all of your advice and assistance. I think I finally figured out what I am doing. Turns out I understand things when I see it on my Windows desktop and just needed to edit information there instead of trying to do it on the Retropie (not sure if that makes sense).
Lastly, I want to say that I FINALLY got the buttons mapped how I wanted them in N64 and this also gives me information on how to do it in other emulators should I choose to do so.
Thanks a lot for sticking with me!
