Dosbox-X core?

Hello,

first of all, thanks for all the work! I was just wondering, would it be difficult to integrate the dosbox-x fork with retroarch? If you already have the svn mainline, how much work would it take to also integrate dosbox-x? Dosbox-x is interesting in the sense that it has the best Win9x support, the other forks/SVN are very spotty on 9x.
