Play retro games using LaunchBox and Retroarch emulator on NVIDIA SHIELD TV Android TV OS 11 tv boxes. It's not easy to configure this emulator but once it's configured it works great.
According to the Launchbox official website, the google play version of it has been given up because there were too many restrictions so today let's sideload it to NVIDIA SHIELD PRO and play.
note: in launchbox UI, press controller L1 to open top left menu, using a mouse isn't necessary.
note: if you use mi box or TCL TV, get launchbox url and use download from url
