Well... it built. I've update the README. Looking around, it looks like a N770 build would work across the board if you had the right packages forward ported - which, in the case of LinuxMCE, you do. The N770 seems to be the odd one out by using libmysqlclient12 - the rest of them have libmysqlclient15 in their repositories. And N770 doesn't run Diablo. But besides a build dependency change, it should build for the N770 too and it should work just fine.
