Today I found If you press A+B+start on game over screen, game restarts with exact same random and settings without exiting main menu

is that allowed for the main category?

The game allows to warp from first stage to skip the first few stages holding A+B inside cinema and the game explains this after some level completion. From my point of view this should be legal warp for any% category but there is a non written rule to not use that warp right now. I didn't find any explanations of that solution in speedruncom forums. Could somebody explain this?

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.
