🛠️ Step-by-Step Instructions
Check the Boot State
If your machine is booted up and playing audio but your screen remains blank on RGB, it’s likely defaulting to HDMI.

Reset the Amiga

Press and hold Ctrl + Amiga + Amiga to reset.

Hold both mouse buttons down as it reboots.

Access the Boot Menu

When the boot menu appears, don’t let go just yet.:

As soon as you click on “Boot,” hold both buttons down again.

Force RGB Mode

This double-button trick forces the system to boot using the RGB display.

You should now see the welcome screen saying: “This is Amiga speaking — Welcome to Captain.”

🧩 Customize Your Setup
Once booted into RGB mode:

Adjust your keyboard and mouse settings

Explore screen mode options

Switch between Low Res and High Res

Personalize your theme

📝 Final Tips
Sometimes older buttons can be finicky. Be sure both mouse buttons are firmly pressed during the process. If you ever get stuck in HDMI again, just repeat this trick!
