only the first link because it's the old version. if you scroll down, there's another.
btw, the documentation is no where near complete, there are some inaccuracies, and generally in it's current stage it'll only be helpful to people doing display list replacements.
to be honest...I actually quit modding about 2-3 months ago. I still toy with my projects for the learning experience, help people out with stuff, and rummage through the n64sdk for other reasons, but don't be expecting me to finish this anytime soon.
