Custom Button mapping Nvidia shield help?

[vnctdj]

Games work decent on nvidia shield. Problem is that all buttons are recognized on my controller except for the analog and d-pad. I don't know if this is a problem with the Shield or emulator not being properly optimized for my device but it's really annoying. I go into the controller setting but why isn't there a way to custom map controls? Am I missing something? Could really use some help. Thanks.

You should use the latest available version here I think
