TAS: Super Mario Bros 3 - Glitch to Ending
This TAS takes advantage of a glitch in SMB3 where taking a pipe in 7-1 the wrong direction glitches the program such that it executes invalid instructions.
By playing carefully, it is possible to use enemy positions and other factors to essentially write a mini-program which skips to the credit sequence without beating Bowser or even entering World 8!
This was the first video to demonstrate a successful game-end glitch in SMB3. Tompa and I made a start-to-finish TAS optimized for speed here: https://youtu.be/PUdHMr2-U9s
I also made a TAS that expands on this glitch to inject new code into SMB3 gameplay, such as a Super-Metroid-style speed boost: https://youtu.be/olivoNlJphg
