Hi, I framecounted dialogs in US TAS and made my own TAS for JP dialogs, and looks like US version is 30 frames faster then JP. Thou input in different versions works different inside lag frames, so in US your inputs sometimes are eaten, so it's not that comfortable.

I've suffered with the US one for years until I got the Japanese version two years ago.

I always felt that the US version was a tad faster by a tiny margin, glad to see this post confirm that.
