Yep! Started out as Xbox Media Player and progressed into XBMC. Then the team made it open source when the original xbox couldn't keep up with the development (HD and such). At that point they made it open source. It grew into Kodi and is the best media player/streamer around! Period!Yep, originally XBMC if I am not mistaken isn't WiiMC a port? You could run it on vWii but it's not very feature and I never had good performance with it back in the day.
Amazon firesticks are great for Kodi and an easy install. I recommend the plugins 1chan, genesis and phoenix. It's all you need for film.
BTW, if you like genesis you should get the latest release from the same team... "Exodus"
