SNES-Killer Instinct...to be honest this impressed me moreso than DKC because it just seemed so un-doable at the time in terms of Arcade-to-console conversion. But it still it had all of the moves and combos(i believe), had a good framerate, and actually had voices. DKC still counts overall, but technically the "wow" work was done beforehand(pre-rendered "ACM" sprites).
Genesis-Sonic 3/Sonic&Knuckles...I haven't seen/played Batman&Robin or Vectorman etc, so I can't give any perspective on those games.
Playstation-MGS, Tobal 2, Tekken 3, Soul Blade, RRT4, Gran Turismo
Saturn-NiGHTS, VF2, Panzer Dragoon 2, Capcon's 4MB CPS2 games(had RAM help, but eh, arcade pefection at home)
N64-Zelda:OoT, Turok 2/Rogue Squadron(RAM help)
GC-F-Zero GX(haven't played Wind Waker or MP series), RE4 apparently
PS2-GT4 definitely
XBOX-DOA3/Ultimate
