I am interested in speed running, is japanese absolutely nessecary for the run?

I.E. Are there exclusive tricks to the JP version that drastically cut down the run time or is it the same across all regions?

Yeah all versions are equal from my understanding, I think there's an extremely minor difference between 1.0 and 1.1 that doesn't matter at this point and time, and all 3 regions are equal (English voice actors, text is like instant)

Iirc Japanese is like estimated 5-10 seconds faster? idk.

I know for a fact there are two text dialogues in Krystal's section that are shorter in JP. One helps make an enemy cycle easier and quicker. That's really all I notice though.

Huh so it's there but only makes something easier / minimal things faster. That's not that bad at least, didn't know there were confirmed sources, thx

thanks for the replies everyone, I am actually taking notes on the route right now.
