I thought that previous hack, "Blurp's Adventure", was a semi-kaizo hack, so I have been making new hack, "Runningball".

This is my hack's title screen.
I haven't made the intro yet, but I made the levels first.

My hack's overworld.
Please ignore the boo above the donut bridge.
It's my hand-made GFX.

It's the first stage, Banzai bills and Rexs are existed like original game.
I also made the level's BG & FG GFX.

The cavern stage. //FG is Black Squirrel's, BG is also not mine.//

I redrawed the SMB3 GFX(It's not shown.) and Cloud drop, Gusty.

Lower route of the 1W stages.
I also redrawed the platforms. [BG's not mine]

The first castle stage is "Blackyoshi's Castle".
Firstly, Blackyoshi's baby is the enemy, then mario rescue yoshi, finally rescued yoshi defeats Blackyoshi Boss!!
