Author's comments and explanations:
This TAS aims to beat Super Mario Bros: The Lost Levels while collecting the least amount of coins possible without the use of any warpzone.

Unfortunately, 5-3 is impossible coinless due to the looping system in the level. It is impossible to bypass the loop object without the use of hacks, tho we (ThreeCreepio and I) were 9 pixels off of doing so. To bypass a loop object, you need Mario to be grounded and have the address $CE (Mario's Y pixel) at the value F0. Collecting a power-up (mushroom or fire flower) puts Mario in a grounded state, which would've done the trick. Unfortunately, power-ups don't have a hitbox between value F0 and F8, making 5-3 impossible coinless, thus making the coin count go up by 16 coins.

3-3 was a tricky one. It was always thought to be impossible, but turns out you can go under the platform that contains lots of coins by using 2 koopa bounces, which requires insane RNG.

Beating the game without collecting a single coin IS possible, but it requires the use of warpzones

feos: Shortened the branch. We're not gonna have Luigi version of this run published alongside. Also any% runs don't mention the worlds they complete.
