1. Raspberry pi zero cannot select OpenGL as resolution 2. Play games with Raspberry pi zero?

No error showed up. After i select a VC4 option, my resolution is still the same. However, when i select other non-VC4 option, my resolution will changed at next reboot.

I tried install and run neverball, the audio runs, but no video showed up.
Or am i need to install an OpenGL driver for raspberry pi zero?
