`word-frequency-analysis.txt` lists the number of times words were either added or removed from a line. This allows us to see that, for example, the word "gnarly" was added to two lines in the US release, but removed from two other lines. `word-frequency-analysis.txt` lists the number of times words were either added or removed from a line.

`dumpspeech.py` is a Python script that reads `norm.exe` and `digi/sound.raw` (not included in this repository) and generates .wav files for each line of dialogue, with filenames that correspond to line numbers in `lang.dat`.
## Preliminary Findings ## Preliminary Findings
The writer in both releases is credited as [Ade Carless](https://www.mobygames.com/person/5209/adrian-carless/). However, the US release has an additional credit for "Additional Script Writing", attributed to [Dennis M. Miller](https://www.mobygames.com/person/183890/dennis-m-miller/), who is also credited as the US producer. This suggests to me that he is the person primarily responsible for the changes to the US script. If anyone wanted to interview someone to get the full scoop, he would be the guy.
