So I have recently gotten my SNES working again, but whenever I boot up Super Mario World everything is perfectly fine in the menu and in the levels but the moment I go to the map, it automatically joins the level that mario is standing over. I'll edit this with footage when I'm able to so yeah.

Edit 1: Also I have cleaned my SMW Cart already and it seems that SMW is the only game that works

Edit 2: Here

I have also started the game, and unplugged my controller and it still does this

What the-

have you been spamming a/b when you save file loads up?

That’s how it looks like If you are, attempt to move around

oooh I never saw that

On the title screen I only spam start, not a or b

same

Weird...

The only thing that comes to mind is one of your rubber buttons has been punctured and is being held down. I'd recommend taking apart and cleaning the controller.

Holding the button down wouldn't enter the level. It checks for the start of an input.
