So, since I already had the video, I decided to take the time and use the translation that already exists to make this video. I had to use punctuation and intuition to figure out what bits were what, so I can't guarantee the subtitles match up to the dialogue on screen correctly, but either way it's at least understandable. Here it is:
Since Chapter 3 is the one I wanted to play the most anyway, I will probably be doing this with all of the cutscenes. I can't promise I can take the time to subtitle all of them (we'll just have to see), but I do plan on at least putting up the footage of all of them for this chapter. Hope someone out there enjoys it!
