Unused Content
The blackout effect used in Screwbot Factory 2 still exists in Rhythm Heaven Megamix. It works almost entirely correctly, with the only issue being one of the spotlight textures having a visible gap in the upper-right corner.

Interestingly, the textures for the shadows and spotlights are replaced with a dummy sheet in Rhythm Heaven Fever for all versions other than Screwbot Factory 2, but are present for Screwbot Factory in Rhythm Heaven Megamix despite not being used.

Regional Differences
In Rhythm Tengoku: The Best+, the engraving on the robot arm is present, as it was in Minna no Rhythm Tengoku. In other versions, it is once again removed.

Miscellaneous
The icon used for Screwbot Factory in Rhythm Heaven Megamix is derived from Screwbot Factory 2 in Rhythm Heaven Fever rather than the original.
