Sorry, I did not have time in the last month to follow this up, neither to merge the pull request to libretro.
Might come back to this in September, but surely not before.
Yes I would be happy to have *one* repo. My dream was somehow to get the architecture dependence out of the core, thus that you can use the core without too much changes in different emulator frontends. You just do not want to patch xxx frontends a time. plus, i would like to have the debug features available in a linux gui. because under wine the debugging is terribly slow (and i have no idea why).
well anyway. currently i dont have the time.
