hi recently installed raspberrypiOS(64bit) for the pi4 im using in the nespi4 case and want to get the safe shutdown script installed so i can use the buttons, since im not using retropie im not sure which script to use to install the safe shutdown buttons, can someone point me to the correct direction please? or do i just use the command line thats there for retropie?
also, which method should i use to move the OS onto an SSD? theres the sd card copier that came with the OS or should i use the method that nespi4 says to use?
