Super Mario Bros. 3 is an action platformer game for the Nintendo Entertainment System.

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 the unmodified (vanilla) SMB3:

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

2. The World 8 hand traps can no longer grab you when traversing over them. (You can still enter them with A if desired)

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.

4. All Koopa Kid boss patterns are now consistent, regardless of when you enter the fight.

For more details and my reasoning for each change, please be sure to check out the Readme.

Enjoy!
