I have a xbox one but I don't know if its faster to speed run on N64

right now, JP N64 is faster for any% and Cheato%. For the rest, US N64 is faster. It is theorised that Xbox may be faster for 100% (by a small bit), but it has not been confirmed.

xbox has faster load times but you can't skip text but n64 has longer load times but you can skip text so probably similar-ish for glitchless runs but n64 is faster for glitched runs because it has more glitches.
