I'm not sure if I'm posting this in the right area, feel free to redirect me but... My sister was messing with the files on my cart and switched the default open program for all .sav files to notepad, I was worried so i started it up and opened a game and it got stuck on the screen that would be right before it created/read the .sav file.... could anyone help me figure out how to switch all of these and be able to open them?
