The MAME/MESS repo is now available at https://github.com/mamedev/mame
You can use GIT client, clone with
git clone https://github.com/mamedev/mame.git
Or you can still use SVN client,
svn co https://github.com/mamedev/mame/trunk
(completely rewritten by RB so people don't get confused by out-of-date info).
