Super Mario Bros. "warpless" TAS in 18:36.78 by HappyLee & Mars608

Ever since I started making SMB TASes in 2008, SMB warpless is the project I value the most. 10 years later, here we are presenting the fifth (possibly the last?) edition of this project.
This was originally intended to be an improvement over my SMB warpless TAS in 2012, but turns out to be a 42-frame improvement over MrWint's warpless TAS which was submitted during the process.

Extra time save in 5-1 & 6-2. Also in 1-4 & 4-4 compared to my last run. Watch comparison video to see how time is saved: https://www.youtube.com/watch?v=SGKmJ...
