Some developers will be keeping a blog over at BlogSpot [here]. We will address what we are working on and communicate with users about new features and branches.
okaygo at mupen64plus.blogspot.com said:We started this blog so that we could reach more of the public, show a little bit of eye-candy, and showcase our work. This blog will be used for showing off some new features, posting about breakthroughs, and giving a general update to our user base. This blog will not be used for discussing technical details, support, or feedback. Also if the blog does not work out as we wanted it to, we reserve the right to scrap it at any time. However user comments are welcome, and we will try to give an update at least once a week.
