However, many subtitles and voice clips aren't used due to their data being removed (Start on frame 0, a frame that's never used as cutscenes start on frame 1. Sometimes the length info is wiped too but not always).
Giving them new data allows them to appear in-game, resulting in a lot of dialogue that you wouldn't normally see outside of looking in the game's files.
The majority of these are subtitles used to describe sound effects, but other stuff includes character dialogue, time stamps and the game calling you a dummy after the credits! Here's a list of what's in each scene, also provided in the readme:
Sometimes it doesn't quite fit, as there are long extra voices in short timespans, but their order in the cutscene is correct according to the script. It's best used with debug controls enabled so you can slow the scene down enough to see them properly. In-level cutscenes and FMVs aren't included as the former is difficult to work with and the latter is impossible to display subs in.
Some used subs/voices have been shifted around a few frames where unused ones overlap too much.
