that's of this time, but you need speed meter next time
Yes, I was thinking Newgame gold% would be better (and maybe that would be better to call that 100% instead gold%) Because you can earn money at the extreme oval on Tempete/Diable GP over over again, then you just upgrade/buy every car.
You're right, US/EU version are faster than JP version at GRADE1 which has around 160km/h(JP version has only 150km/h)
I tried US version of Rage Racer with emulator, there is almost no difference between JP and US. I got 2'35 or 2'36 at Mythical Coast with US Ghepardo in 2018
Anyway, thanks for answering and praising
Do I need to upgrade every car to class5 for both of NormalGP and ExtraGP? Or Can I play NormalGP as fast as possible, then I can choose upgrading every car to class5(and Devil car) at DiableGP on ExtraGP?
