HardCore was the first DOA game I played, after a lot of year I played DOA4 then 5 but seeing this reminded me of what a bitch my bae Ka-sushi sounded like back then....
Dead or Alive 2: Hardcore has a "Turbo" option available in all games modes (aside from "Story"). It essentially speeds up the game. It takes some getting used to, since reacting to certain strings and pokes becomes much more difficult. Some combos get fairly tricky as well, such as Hayabusa's Izuna Holds.
Forgive my shoddy play. It's hard to readjust to an old game now that I instinctively try to play DOA5U Ryu, not to mention that I've never quite gotten comfy with the Turbo setting.
