Also here are the base rules: Must not press the R or ZR buttons Timer starts when you press OK on the track or cup selection menu If you are playing on the category with items, you can play on a Grand Prix.
VS Mode rules:
No Teams Normal Items if playing on the Items category Hard COM All vehicles In order
The idea is very simple: finish a certain amount of tracks without pressing R or ZR, which means: no drifting, no jump boosts and no hops. You can actually still drift by simply turning the L sitck sharply, but it's much difficult. To avoid accidental ZR or R presses, disable the buttons on the Switch configurations menu. It's very stupid I know. (reposted here becuse people told me)
Edit: Just did a run of the Mushroom Cup, 150cc, Items and got an 10:47
Hey, why we don't use IGT instead of RTA? It would be closer to how it works on Genesis and the 2013 ports.
