@jor2404 Today I was also trying to solve the blackscreen problem. I did all steps described in this forum but without success. I use it for running Steam and after selecting Moonlight the Steam was executed on my PC automatically but at my Raspberry there was only black screen again.
Then I started following. I downloaded and installed latest fresh Recalbox image and did the Moonlight pairing with my computer. Everything was working at first try and games were running. But I do not wanted to configure whole Recalbox and Kodi again for the new SD card. So I made a backup of all files in /share/system/configs/recalbox/moonlight. Then I put back my old SD card deleted all files in share/system/configs/recalbox/moonlight and copied files from working card backup. After this step my old SD card started working and Moonlight is running games correctly.
One hint: When I tried to delete the files from card if was not possible using the shared folder. It was necessary to stop the emulation station and login as root directly at RPi computer.
