+    * Most TFT LCDs will need the fake KMS driver activated instead of the real one, ''dtoverlay=vc4-fkms-v3d-pi4''
   - Boot up Batocera on the Pi, access it [[:access_the_batocera_via_ssh|via SSH]] and execute the main driver binary. If the stars align and you are successful, you'll get an image on your screen: {{ :tft_screen.png?500 |}}
   - Add the command line you used to start the drivers to [[:launch_a_script#launching_a_script_one_time_only_early_in_the_boot_process|a custom early boot script]]. If this doesn't work, try using [[:launch_a_script#launch_a_script_one_time_only_during_boot|the later post-boot custom script]] instead (you'll lose out of seeing the splash screen if you use this method).
