Wow. This took longer than I thought. I'm finally done with the NPCs. These files were more complex than the normal story files. Here's a little insight into the files.

The first 2 bytes of each script_data file indicate the number of pointers. In this example there are 5. Then the 5 pointers come as 2 bytes as marked in color here. At the G-Center, Bullet Shops, Score Shops and an NPC in the laboratory there are additional pointers in front of a few text blocks. I had to find this out first. Well now it's done and I have completed a big task.
