@chuskie yep it may be an OS incompatibility. Usually on Windows and retropie the directory format may differ and the build fails to load the images. Tried to check Kodi error log? If not try looking in these directories for the LOG file:
Android: {storage}/Android/data/org.xbmc.kodi/files/.kodi/temp/kodi.log iOS: /private/var/mobile/Library/Preferences/Kodi/kodi.log Mac: /Users/{my_user_name}/Library/Application Support/Kodi/kodi.log Windows: C:\Users{user_name}\AppData\Roaming\Kodi\kodi.log Linux: ~/.kodi/kodi.log OpenELEC: /storage/.kodi/kodi.log OSMC: /home/osmc/.kodi/temp/kodi.log XBian: /home/xbian/.kodi/temp/kodi.log Raspberry Pi: /home/pi/.kodi/kodi.logAlso take a look at this tutorial on [deleted].
