Accepted answer: no
I play San Francisco Rush 2049 (on Dreamcast, if it matters) with a friend, and we want to unlock features together in 2-player mode.
Is this even possible or do you have to play in single-player mode?
I read that you can unlock a new single-player mode, when you get 1000000 points in stunt mode. I assume that you don't have to get these points in one session, as it seems impossible. The points seem to get saved in the player's score table, so you'll have to collect these, I guess.
How do you get new stunt levels? Do you have to collect all gold and silver coins? Would only one of us need all coins, or do we both need to get all coins? If only one of us has all coins, can we nevertheless play the new level together?
How do we get new cars? Only in race mode? Again, is it possible to unlock them in 2-player mode?
Are there new battle maps or even weapons to unlock?
Anything else?
