Yes and No. There is a Krypton branch which works fine so far but at the moment there is a nasty bug in Kodi 17. If you use the Krypton branch you will have a lot of missing textures while using.
This is caused by Kodi 17. It seems Kodi 17 looses variable content. And because Madnox is so big but good , Madnox have a lot of variables and these variables are used to control the textures.

The Madnox team is working hard to find a solution.

So you have to life with it at the moment or use a different skin.
