English is the lingua franca of this community, so it's polite to submit movies using the English versions of the games, when possible. Now, I'd add a caveat to the above -- if language is basically irrelevant (e.g. in a game like Gradius), then I don't see why a Japanese ROM couldn't be used. I haven't watched this movie, though, so I couldn't say one way or another.
The movie desynchs with the (U) version, so they are not exactly the same. There might be no other difference than the intro timing, but I don't know for sure. (To me it seemed that the Japanese version has faster intro. Just a guess based on how the movie desynched.) Maybe the version shouldn't matter that much, but ignoring the versions can cause problems in the future, when comparing movies to each other. Even minor graphical differences have caused interesting discussion here. I would recommend editing the file to pass the (U) intro, just for fun and testing. Playback with different versions can sometimes result in surprising findings about the game.
Maybe I missed some detail, but couldn't it have been faster to use the Star Fire as the final hit in the "wall boss" refight? Now you used Comet Flash and it seemed that the three targets got hit in sequence as opposed to the possibility of hitting them simultaneously with Star Fire.
My TAS hand. Stretchy.
Just wanted to say that your WIP's are awesome and they've helped my console run of the game a ton so far.
I've never really liked using a gamepad for anything other than console gaming. In fact, if given the choice, I probably would prefer the keyboard for that as well. There are two games for which I can legitimately say I'm pretty good at them: Rockman and Street Fighter Alpha 3. I'm no longer playing them, but when I did, I used a keyboard. I played a pretty mean V-ism Akuma, too...
