While Recalbox with Pi2Scart doesn't automatically detect your TV type, it does default to a safe mode compatible with both 4:3 and 16:9 displays. You'll likely need manual adjustments for optimal output on a specific CRT, but the initial settings prioritize preventing image stretching or cropping on either aspect ratio.
This means you'll see black bars on a widescreen TV, but your classic games will appear correctly on a 4:3 CRT without further configuration.
To set HDMI output for Recalbox External HD setup, connect your laptop to the TV using an HDMI cable. Ensure the TV is powered on and set to the correct HDMI input. Boot up your laptop with the Recalbox External HD connected. Once booted, access the Recalbox settings menu, usually found in the main menu or through hotkeys.
In the settings, navigate to the display or video options, and select HDMI as the output source. Adjust any additional display settings as needed. Save the changes and restart Recalbox. The video output should now be directed to your TV through HDMI, providing a more comfortable gaming experience.
Unfortunately, deleting emulators might be irreversible, so consider hiding instead. To hide unwanted emulators from your Recalbox 8.1.1 main menu, you can either remove their ROMs from the corresponding system folders within the "share" drive, or (if your Wiki mentioned it) edit the "menu.conf" file located in the "Share_Init" folder (accessible through File Explorer on your connected PC). Remember to refresh the game library after making changes. Hope this helps!
