There is a developer CVS, but you must get permission to download from it. It is mainly for developers only. If you want to update your code, there are many fixes posted in this forum and the Bug Report forum that would probally be in the developer source.
http://cvs.biosprite.net/ is the public dumps, which are the dumps whenever khuong is high on crack, but their wont be another dump for a while because some dumbass made a big deal (or something like that) about how the developers messed up his hard work or something along those lines.
