Kaizō Mario 2
Rather than being an imitation of the infamous Kaizō Mario World hack, this is merely a hack with all new levels for Super Mario Bros. 2.

Experienced players should find this to be challenging, but not insurmountable. Abstaining from the use of save states is encouraged.
It should be patched to a ROM with md5

Thanks to ALXR for creating jGreatEd, the tool I used to create this.
