I have a Raspberry Pi 4 connected to my TV. I have Kodi on the SD card. I have a USB strip connected to the Pi 4. So i have a Portable USB drive with all of my MP4 Videos on one and my retro games on another one, all connected to the USB strip. How can i install RetroPie image on the USB drive along with my games, so my games and RetroPie would be on one drive ?
