Sadly I bought the Yoka KB2 S912 Android Box.
Is there a chance to get 3D MVC to work?

It always plays my 3D.iso Files as 2D without asking me,...

I don't believe any AMLogic device plays 3D isos as Frame Packed full resolution. There is some support on the S905 for Half-resolution replay - but I don't know how popular it is. For full 3D MVC replayed Frame Packed in Kodi you probably need a Pi or Intel+Windows?

Supplement: The Half-resolution support is only given on some Jarvis builds, i.e. Kodi 16.x (e.g. LibreELEC 7.xx). Since Krypton there is no way to get MVC support, that I am aware of.
