I tried the new function to skip cutscene/movies: at the first FMV while doing that the music doesn't start, it does only after first battle. Then you swap map and come back on the first map and you are able to get another Potion from the same soldier (btw they share erroneously the same model of the train guard.)
Seems working so far with sfx memory off, will update.
Also, I know it's already mentioned in reunion database, but jeez the model polygon going over the battle menu it is annyoing.
