Will The New Online Expansion Work for runs cause it has the original game now instead of the 3d all stars verison?

i just did a quick 16 star no lblj and the only main issue is the controls that can be changed in the button mapping settings

That shouldn’t be an issue. Top runners map their controls for other games. Gymnast86 does this for SSHD. Since it’s an official feature, it’s allowed.

Edit:Also just looked at the Metroid Dread leaderboard, it explicitly states that remapping controls via the menu is allowed.

Does the NSO version of Mario 64 has input delay like the Wii U VC?

yes

the input delay feels worse than on wii u vc

Is there a way to use the nso 64 controller via a wired connection?

yeah tobithd but i think that’s gonna be a thing to get used to if runners play on the switch NSO

I think no one is going to fully switch to switch Sup1

So yeah Switch VC doesn`t seem to be viable for speedrunning just for input delay alone (8 frames or 135 ms from what I heard).

I haven't had any delay problems with tricks on Switch VC.
