Mega Man (NES): A hack that will change the title screen into this:

I actually did just that years ago when I was fiddling with the idea of a demake of Powered Up.
Unfortunately, that work is long gone at this point. But at the very least I can say that it wasn't difficult to accomplish, IIRC.
Note: Also, what you refer to as SMB2U I refer to simply as SMB2. And forgive me for going off-topic, but personally, I think there ought to be only one SMB2. Too much confusion to have two of them out there. In my opinion, SMBTLL (AKA SMB2J) just doesn't cut it since it's way too similar to SMB, so I think the SMB2 the West got should be the only one. Just my opinion.
I am generally of the opposite opinion. Though in reality, if you consider the timeline of events, SMB2u should really be SMB3 and SMB3 should be SMB4, etc... For me I just call it SMB2u in shorthand because everyone for the most part knows what I mean.
Plus, you can also consider that when they finally released the original version on it's own world wide (not part of a compilation) they didn't bother giving it an alternate title. It is just SMB2.
No "Lost Levels", no "For Super Players".
Of course, that could just be laziness!
