Thank you both for your fast responses. I really appreciate the help.
I took your advice Escorpion, but to no avail. I tried basically every kind of setting possible. They just won't save. I don't know how to make Nintendon't save a new config file. When I delete the config file I somehow created after hours of trying, it just refreshes. After like 15 tries, I got Nintendont to save once. Don't know what I did. I forgot to enable the memcard emulation though, so I missed the most important thing!
Sonic Angel Knight, I just stick with the default size. 251 I think? Nintendont refuses to save my settings regardless. Even if I only toggle one thing, like the widescreen, it doesn't save the changes I make at all.
I've been pulling my hair out over this lol
