Super Mario Bros. (NES): 256w - Glitch levels that normally crash

Codes down below in the description.
In Super Mario Bros. for the NES, there are several glitch levels that just crash or "black out" upon loading the level. This can be (somewhat) avoided by freezing the value of address 0725 to 00. The level will be only loop if it's frozen to that value. Once this value is unfrozen, the level will crash the game upon entering the next screen.

I always love seeing the game read "Ram Data" as "Level Data."
it's like watching a little kid make a mario maker stage.

Great video, man! :)

The first has underwater 6-2 enemies, the second underwater 5-3, the third underwater coin heavens A, and the fourth underwater 4-2.

[@jongandee4876]

Why did the text at the top of the screen move around when the game crashed?

[@Dekkiedot]

That is generally something the SMB1 engine does when the game crashes.

Their castle variants have world 3-3, 6-2, 2-1, and coin heavens B enemies.

[@apurim7698]

What caused the game to crash? Is it a glitched block, a glitched enemy, or some other factor?

[@Dekkiedot]

Likely a glitched block.

[@ottothediplocaulus6584]

Are you sure these are glitch levels? They just look like Mario maker levels to me.

[@ktrmambiance1627]

W68-6 (4C/CC): Loads the same enemy data as level ID 09/89 (in-water 1-3/5-3)

[@Dravenick]

0:48 Mario wants to move on, but the game said, "Nope" and then crashes.

[@JoeRoe-wp2mu]

I'm confused. World 52 looks very different in this video: ruclips.net/video/0TaNkMjGuV4/видео.html

[@MaxEditsSpore]

There is no goal, because the levels were never intended to be beaten

[@Dravenick]

0:15 Mario choose to enter in a pipe the wrong way, and did it, but the game crashes.
