Here is the list of all the address locations I've figured out in the Prophet VS. This may change as I discover more. The ones in (bold parentheses) are code locations modified or changed in my own versions of the code, [bold italic brackets] are ones I don't know or aren't sure about yet. Ones with a * are the main called locations in the code.
This is based on v1.2 and up. Some locations, especially the working memory, are different in 1.0/1.1. Some locations are different in the diagnostics section as well. All are word length.
