Thanks for bringing the new cores to our attention, I'll get them integrated in Kodi when I get a chance.

What is mgba core? Don't we ship mgba already?

I added yabasanshiro: kodi-game/kodi-game-scripting#120, however it requires OpenGL so I'll hold off on adding it to Jenkins and the mirrors.

The other cores require OpenGL support, so I won't be porting them until Kodi has hardware rendering.
