Ok this is a bit embaressing,
1.all the controls except the back button work with splashtop gamepad THD natively, i had a problem with the game i was using to test (RAGE) thats my bad.
2.In Tincore however, I was unable to map through it with D-pad and analog sticks.
in x mode all button were mappable with the exception of
D-pad and back button and analog. (do i need to buy the analog sticks? i bought analog collaboration, i will try again)
3.The only drawback is the known right stick sensitivity issue other than that its streams very well, controls awsome:)
(analogs are better than the ones on my shield)
I guess in the new version of Tincore maybe we can choose a single button to map,and use the rest natively, it would be perfect.
