As someone who published both Super Mario Ball and Bubble Ghost, the main reason why I show the title screen in my encodes of Bubble Ghost, but not Super Mario Ball, is because Bubble Ghost actually shows the credits if you let it idle a bit (i.e. not hitting Start).
In Super Mario Ball, the sequence goes like this (starting from game boot): opening -> title screen -> high score ranking -> attract mode -> title screen -> high score ranking -> attract mode -> title screen -> high score ranking -> opening (and so on). After the movie ends, the sequence skips the initial opening directly to the title screen, then the sequence should be similar.
Incidentally, I cut my encodes for Super Mario Ball at the fade-to-white of the high score ranking (the one that shows two screens after The End, which leads to a rather ugly cut). IMHO, the final input should be at the last menu before the high score ranking, i.e.
this one.
Therefore, I agree with feos in that the encodes for this game should end on the high score ranking, as I don't really see a reason to show the title screen at the very end.
