Super Mario World - Vanilla Secret 2 Secret Exit Glitch ( new exit )

.I don't know much about SMW but I was fascinated with the new exits and glitchs and decided to find more of them. Okay, lots of cheats were used, such as: Store keyhole in itembox, store key in itembox. Turns out I found a new "exit". It even counts in the menu, has sound and look very close to bowser castle, something happens there, i will check it later I'm not very familiar with this game, but I think it's a new exit anyways.
