Not the UI itself,I specifically mentioned the touch controls,I mean the ones enabled via switching the “touch” profile to “everything” which works fine when pressing each of the buttons and even moving the analog stick part works smoothly. Though I guess you mean that RetroArch runs on a purely different engine than the use of Android’s UI engine,so thats what got something disabled.
Touch says “no” in 7zipper 2.0’s device info list,but that may be similar to the Play Store (requires touchscreen) compatibility filter. In an unrelated note,enabling the mouse support in RetroArch makes a white mouse pointer appear,but I can’t control it from the looks of it.
My first thought would be to blame Google since they are the ones who removed Shield Controller touchpad support in SATV and now they must have removed the emulated touch part that RetroArch uses for Retropad and the like.
I have been fine with playing the Classic Mario World 3 hack that was recently released,having the Retropad overlay disabled,but whenever an update is made,I will gladly test to see if it works again with that change.
