Introduction
There are over a dozen levels in the SMB3 coding not found in the actual game. They can be accessed with a ROM hacking program. Someone at themushroomkingdom.net made an IPS patch that allows access to these "lost levels".
Patch to SMB3 PRG1: http://themushroomkingdom.net/smb3_lost.shtml
At the website, you can also find some level maps of these "lost levels".
Notes
Emulator used: FCEU 0.98.15
This is my first TAS. I made a few screw-ups on the overworld movements. Sorry about that.
Level comments
Level 1: I run to the right at the start to show what's at that part of the level. Then I run back to the beginning and take the pipe to the rest of the stage.
Level 2: Another intereresting level. At the end, there is a pipe attached to a wall. The pipe leads to a boring Coin Heaven. Flying over the big wall leads to the "real" goal. I tried to walljump over it, but I couldn't.
Level 3: I get a Kuribo's Shoe here. There is an interesting glitch involving jumping with the shoe. After falling (not jumping) off a platform, you can jump once again in midair because the game thinks you are on the ground.
Level 4: This is like a harder version of 1-5. This turned out pretty good, I think.
Interesting note: The angle of a "slope jump" exactly equals the angle of the ground that I slope jump at.

Level 5: This level just has a Tanooki Suit block. I get it and take the pipe to exit the level. Using a Walk-thru-walls Game Genie code, it is possible to go through the walls to see more Tanooki Suit rooms.
Level 6: Interesting level. I think this turned out well.
Level 7: World 7-4 redux. Autoscrollers are kind of boring, but I think this turned out pretty good.
A "lost" enemy appears here: Gold Cheep Cheeps swim faster than normal ones and swim in groups of three.

Level 8: A pretty interesting level. Getting the third of three matching panel cards here causes a graphics glitch: When the big "fireworks" powerup appears during the fanfare, there will be a bunch of scrambled letters in the background.
Level 9: A sky level! Another lost enemy here: Green Parabeetles are faster versions of Red ones.
Level 10: A "lost" Coin Heaven, maybe?
Level 11: A harder version of 1-6.
Level 12: Much shorter version of 1-6. No exit here, so I die in a pit to exit.
Level 13: Copy of Level 12, except Mario's starting position is lower.
Level 14: No enemies, pits, or exit here. The big jump I make about halfway through is to show some of the black glitchy background. I reset the game to get out.
Level 15: No enemies, pits, or exit here either. Some "lost" cloud platforms are here. The Bullet Bill cannon doesn't fire anything. I reset the game to get out.
...and that's it! Hope you liked it!

Improvements:
- Fix overworld mistakes.
- Possibly some routes improvable, such as the water in Level 2 and/or Level 8.
EDIT: Run cancelled, re-doing with improvements.
