Meter Dunk
yew2K page 14: hold L1 or Circle and the right stick stays pinned down so the dunk meter fills; release stops it.
A yew2K page (page 14) with options Off / L1 / Circle; ships Off, yew runs it Off. It is hold-to-time, 2K26 style: while you hold the chosen button the right stick stays pinned down so the dunk meter fills, and releasing snaps the stick neutral to stop the meter.
