Nintendo GameCube aspect ratio fix

[retroboy]

May i ask for a request please, or at least someone could help me out on how to fix it? I have noticed that Super Mario Sunshine and Paper Mario are in a 16:9 aspect ratio instead of a 4:3, and it doesn't  look good on the frontend.

I am not aware if there are more, i will check it out next week. ¿any suggestions? ¿or way on how to change the aspect ratio? i know you are busy.

Thanks for all the work and effort
