Description
------------------------------------------

This hack is an extension of Super Mario Bros. 3 - No Autoscrolls designed with additional tweaks and adjustments to improve the SMB3 speedrunning experience while preserving the feel and charm of the original game. Specifically, the following changes have been made compared to vanilla SMB3:


1. All autoscroller levels have their autoscrolling disabled, including 5-9. (see the No Autoscrolls hack for more details)

-For those familiar with SMB3 speedrunning, the autoscroller levels are notorious for being tedious and predictable to the point where they can be considered 'cutscenes', but with constant input being required to avoid taking damage/dying. With autoscrolling disabled players can speed through those levels at their own pace, reducing the time taken to complete the game by up to 40% depending on category.


2. The Star and Music Box items have been enhanced to counter the World 8 hand traps. Simply use either item on the world map to become immune from getting grabbed.

-World 8 is infamous for being the killer of many speedruns due to hand RNG, especially in the No Wrong Warp category. Rather than disable them entirely I decided to preserve the original mechanic instead by providing a counter through the use of items. The Music Box was a perfect fit for this, but I decided to include the Star as well for categories that do not obtain a Music Box (like No WW).


3. Hammer Brother position and movement has been adjusted where necessary to prevent/greatly reduce the chance of 'marathons' and excessive marching in general. Additionally maps have been slightly modified in places in order to guarantee avoidance of optional Hammer Brother encounters.

-These enhancements are intended to reduce the influence Hammer Brother RNG has on the SMB3 speedruning experience (most notably, the 'runaway' Bro in World 3). This is done by expanding the list of 'unallowable' tiles that they cannot pass through to include the following:
-Level 5, 6, 7, and 8 (all worlds)
-All Ground (yellow) Fortresses
-The World 2 Quicksand Level

Additionally, the following adjustment have been made to the world maps:
-The World 6 Bro with the Jugem Cloud was moved between 6-9 and 6-10 to prevent potential marathons in World 6. The Cloud Bro was chosen because statistically it was more probable to encounter it in the new area while also avoiding the other Bro with the Star in its default location.
-The World 3 Bro with the Hammer was shifted up one to reduce movement needed to reach him (assuming no deaths).
-The World 5 ground half was adjusted to separate the two Hammer Brothers there.
-The Spade tiles in World 2 and World 6 were moved in order to guarantee that the Bro with the Music Box in World 2 and the Bro with the Star in World 6 were avoidable.


Note that submitting speedruns using this hack on the vanilla leaderboards is strictly prohibited. The goal is to create separate leaderboards specifically for this hack in the near future.

Enjoy!
