4. Download the terminal background image (you can use any you find). Here is the one included in this repo:

   

5. Save background.png to %localappdata%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\RoamingState.

6. Under your profile (PowerShell, Ubuntu, Command Prompt, etc.), add:

{
    "guid": "{xxxxxxx-xxxx-xxxx-xxxx-xxxxxxx}",
    "hidden": false,
    "name": "PowerShell",
    "source": "Windows.Terminal.PowershellCore",

About experimental.retroTerminalEffect

The "experimental.retroTerminalEffect": true setting in the profile above enables a CRT-style visual effect (inspired by the Microsoft Retro Command Prompt) that adds scan lines, screen glow, and subtle curvature distortion. You can disable it by setting the value to false.

You should be good to go!
