my super mario all stars + super mario world is acting weird

when ever i try to play it the screen distorts in the bottom left corner and some what across the bottom. I know its not my snes because it doesn't do it on other games i try to play.

Take a picture of it so we can see exactly what's happening.

Speculation.  Try cleaning the contacts on the cart and system.  Also try to test it on a different SNES to make sure it's the cart and not the system.

something like that happened with my super castlevania game. i took it to a friend who had a set of tools to open the cartridges and he found water inside. not much.. just a tiny drop.. not even a full drop. i did not knew how it got there but the game was all flashy and the graphics broke in many parts of the screen.  i try cleaning it and using the hand dryer to evaporate any residue but i did not fix it. had to get a new copy.
