Hey ThornMartin! This is great news. I'd be happy to help you out with tips/ideas if I can.
This is an excellent start, though.
What I would do is to look for the pointer table by searching the ROM for a pointer to the strings. You mentioned that the text starts at "64B1D". Well, to the NGPC, this would actually be 0x264B1D, because the low 16mbit ROM chip is mapped from 0x200000 to 0x3FFFFF.
When I worked on CFC2, we built tools for it. However, there are string editing and pointer manipulation tools out there. You might want to look into those, because it might be an easier way to start.
But, to search for this first string pointer, you'll have to keep in mind that the NGPC is little-endian. If you're using a regular hex editor, you'll want to search for 1D4B26 (or 1D4B2600).
When you find the string pointers, it will look probably like a whole series of similar values. Let me know what you find and we'll see if we can go from there.
Awesome project! Thanks!
