I'm spent all day getting far in Super Mario world and then my foot hits the game and the screen is a partially black. I reset the game and my save file is now reset

But somehow the 2nd file is still there?

Is there any way to fix this?
have you tried up,up, down, down, left, right, left, right, b, a and start?
Been in Japan since August, no fucking money left!
You must travel to the distance mountains on the planet's edge, while carrying the virgin princess. When you arrive you must talk to the Great Behemoth and complete his task.

Only then can you play Super Mario.
try loading a different save and kicking the super Nintendo again it might remove that one and bring back the other one (no lie, this is what i did when something similar happened to me on legend of Zelda)
Second file is still there because you weren't using it. If both files were missing, I'd tell you to take the cartridge out and blow on the connection, that usually works for me.

But no, you're fucked.

Take a break. Play some DKC instead. I'll give you a cookie if you can beat it under two hours.
