@memememess No idea. Naturally, it needs an internet connection (at the end of the day it is an ONLINE translator), but after that...who knows. Not me, anyway. For example, in my case it sometimes kept translating....until it no longer did, at which point restarting the game brought it back to life. Do note, though, that the longer the dialogue line - the longer it can take to translate; kinda obvious when you think about it, but not particularly when you are unfamiliar with the thing. Not "1 hour" longer, but a few seconds difference does exist.
I think someone made their files available...somewhere in the thread - you could grab those, I suppose. Or put the game on the backburner until KG releases their translation (and probably a fix or two - they seem to be the Bethesda of H-RPG translations).
