Hi guys, I'm at one of my wife cousin house and we are playing SNES, but we are trying to play now donkey Kong country 3 and when we try to start the game this sign appear

And won't let us play it.
Someone knows why this sign appear and how can I eliminate to start playing it. We are playing it on an original SNES, never mode, never repair, original from factory, one owner since 1993
Any help on this will be appreciated
Thanks
