Lakka has no kodi, Lakka has only Retroarch and Its GUI. PS3-Like
I know, and it works like a charm, but for instance on my 905 box I'm using a plugin in Kodi to start retroarch. So i was just wondering if you could add retroarch on LE with the required libs and find a way to start it, though I'm trying to multi-boot first with Lakka on USB, which will work good enough
