This is my attempt at a tutorial explaining how to perform unintended exits in Super Mario World. Super Mario World is a notoriously glitchy game, allowing the player to go beyond what was intended by the game designers. Normally, there is a total of 96 exits in the game. Over the years, dedicated gamers discovered several unintended exits (see https://pastebin.com/wqk0KfbM for list).

I want to find novel unintended exits. For this, I used unintendedly spawned Key and Keyhole in the level. Triggering a secret exit in levels having only a single normal exit usually activates the normal exit of the next level. Here, I wanted to try it in Yoshi’s Island 2. First, we have to perform the Powerup Incrementation glitch to get Mario at Power Status 8 (see    • SMW ǀ Unintended Powerup State (Power...   for tutorial). At Power Status 8, go to Yoshi’s Island 2 to get the Key in the item box (see    • SMW ǀ Unintended Item Spawning ǀ (Win...   for tutorial). After, repeat Powerup Incrementation to go to Power Status 96. This Power Status allows Mario to spawn a Keyhole at the Goalpost if holding a PSwitch (see    • SMW ǀ Unintended Goalpost Item Spawni...   for tutorial). To trigger Yoshi’s Island 2 secret exit, first enter the level (already cleared) with Yoshi. Spawn the Key. Place Yoshi with the Key in this mouth just behind the Goalpost. Grab the PSwitch and jump into the Goalpost to land on Yoshi. The PSwitch will transform into a Keyhole. The Keyhole ‘falls’ on us, triggering the secret exit! Unfortunately, triggering Yoshi’s Island 2 secret exit does not add a new exit in the game file… :( This glitch should trigger the normal exit of the next level, which is Yoshi’s Island 3. But because Yoshi’s Island 3 is also cleared, nothin happens…

Hope this video can help you in your quest to master SMW famous (and awesome) glitches.

My setup: I use an original Japanese Super Mario World cartridge played on a Super Retro Trio 3 Console (PAL version); I thus played in RealTime Attack [RTA] without Saved States. Crappy video (and sound) captured using an ‘EasyCAP’ USB adapter (SVideo signal) and ‘Honestech VHS to DVD’ software. Video editing done using Shotcut free software.
