I've been looking for a few ROMs - namely Finger DDR, Dance Y2K, and Super 2-in-1 (specifically the dance game, if you haven't noticed a pattern here :p) and this is the best place to ask. Someone on here posted a link to a ROM for Finger DDR but unfortunately the link has expired and I didn't want to bump a 2-year-old topic to request a reup.
Thanks in advance!
