Bugs:Super Mario Bros. 2 (Famicom Disk System)

This page details bugs of Super Mario Bros. 2 (Famicom Disk System).

Hmmm...
To do:
A perpetual death checkpoint in World C-3 that was disabled in Super Mario All-Stars (that is, if that counts as a bug).

Letter Desync

The part of the nametable that is "locked in place", so to say, for the HUD is only tall enough to account for number tiles which are one pixel shorter than letter tiles. As a result, on Worlds A-D the bottom pixel of the letter in the world text scrolls with the level instead of being locked in place like it should.

This bug is not present in the Famicom Mini version for the Game Boy Advance.
