@SmoothNobody Glad to see you got Remote package Installer working.
Once the game has started to transfer you can safely press the PS button on your controller and it will take you back to the main menu on the PS4.
Here you will see the game you are installing with a progress bar.
When you want to install another game, open the Remote package Installer again and repeat the process.
Is your PS4 connect by Wifi or by a LAN cable?
If it is connected by WiFi the transfer speeds are slow and it would be quicker to use a USB drive.
If you are connected by a LAN cable the transfer speeds are significantly increased and are much faster than using a USB drive.
