I've found (like, a year ago...) an unused scene in Shenmue I, that I've never seen before!
Unfortunately, it seems to belong to a really old beta map, and the textures of the buildings get in the way, so I've to remove them in order to see the characters clearly.
I've to set the levels of expectations, though: it's short and a lot of the voices/lip syncing and lines are missing. But still interesting!
There are three recordings of the scene: 1) with some textures removed to not get in the way (because the camera's movements are not consistent with the current map), 2) with nothing removed/ripped, 3) with using the beta/old map of Sakuragaoka.
Back then I was trying to change the map with another (like, with Dobuita's) but after some tries didn't make it and then 'forgot' about it. Give it a try, too, if you want and see if something changes or look better. Probably, that scene takes place in another area, or in one that is not even in the data.
