Understand it, needless to say i havn't any way to check with an original pcb. Yes, the screenshot I originally attached was taken just printing the screen, good to know the F12 shortcut in MAME. I used only MAME version .216 before the .217, no luck to detect regressions.
It's only my opinion, but it's hard to believe the game was really missing that part, so I just checked the other related game: taisen hot gimmick integral, which combines all the girls from the series gimmick to gimmick kairakuten, and in it there is all the working animations. Not a sure thing, but probably the taisen hot gimmick had them right, but still... who knows!
Thank you anyway for your answer, maybe in due time somebody will look after.
P.S. in taisen hot gimmick kairakuten there's a missing animation for the diving girl too (totally skipped).
