I want to know who can perform the fastest race of each course

In time attack mode?

Could be interesting. I would definitely play more if I could focus on just one race at a time. But by "more" I mean "more than not playing at all" 😃

it can be by any 3 race modes but time attack might be the best

If someone can write out a list for me I can put these up for PC, PS and PS EMU :)

Speed Bay, Dirt Arena, Rock Forest, Great Wall, West Way, Lost Ruins, Fun Fair, Sea of Sand, Red City, Snow Ride
