This is painfully obvious all levels with a defined "ceiling", completely unedited and a good 3 tiles off the top of the screen, as well as other levels with normal pipe transition entrances, where they could have been easily shortened to 1 screen.
It's because the PC-8801 and the Sharp X1's screens aren't as tall as the NES and SNES' screens.
It's even like that in the SMB1 hack version of the game:
Issues that I've found:
An invisible coin block should be here, but it's missing. As well as the 2 invisible blocks that should be close to this part.
The pipe is cutoff!
The firebar on the left is partially invisible due to sprite tile limits.
Part of the platform disappeared due to sprite tile limits.
In 2-3, this platform that falls when Mario steps on it has glitchy graphics.
In 4-4, when you beat it, the Course Clear! scorecard appears and it moves along with the background.
