Hi etabeta

I've run this: Super Mario Bros (Pirate).nes and most smb carts I've tried

There seem to be some input errors. normally happens when I lose a life. when you go left or right it is as if the controls sudenly gets stuck in that direction. meaning mario only stops if he meets something blocking his path.

also on some of the pirate carts the levels can randomly change, but this only hapens every now and then. sometimes mid level
