Really nice project, too bad the picture are really small on your site.
About mGalaxy, better to ask mgalaxy himself ^^, but soon a new version, with more system on the system base but I don't know the new features.
For the moment I have a solid base on my "Retrocube" (the name is from an other user from the site, copyright inside
) no more changement on this side, I m helping for a new emulator, and waiting for new emulated system, perhaps Lindbergh or a better N64 renderer.
I m too on a personnal project on raspberry, but nothing to see with emulation
