"Most beings can run it like "./mednafen-server standard.conf >logfile &".

Windows users can run it some other way.  A batch file with absolute paths, perhaps?

Reminder:

"To create a service for Mednafen on a Linux system, you can follow these steps:

    Create a service file:
        Open a terminal.
        Navigate to the /etc/systemd/system/ directory: cd /etc/systemd/system/.
        Create a new service file using a text editor, such as nano or vi: sudo nano mednafen.service.

    Configure the service file:

        Add the following content to the mednafen.service file:
        plaintext

        [Unit]
        Description=Mednafen Server
        After=network.target

        [Service]
        ExecStart=/root/mednafen-server/mednafen-server /root/mednafen-server/standard.conf
        WorkingDirectory=/root/mednafen-server/
        User=root
        Restart=always

        [Install]
        WantedBy=multi-user.target

        Modify the ExecStart line if the paths to mednafen-server and standard.conf are different on your system.

    Save and close the file:
        In nano, press Ctrl+X, then Y, and finally Enter to save and exit.
        In vi, type :wq and press Enter to save and exit.

    Enable and start the service:
        Reload the systemd daemon to ensure it recognizes the new service: sudo systemctl daemon-reload.
        Enable the service to start on boot: sudo systemctl enable mednafen.
        Start the service: sudo systemctl start mednafen.

Now, the Mednafen service should be running, and it will automatically start on system boot. You can manage the service using the following commands:

    sudo systemctl start mednafen: Start the service.
    sudo systemctl stop mednafen: Stop the service.
    sudo systemctl restart mednafen: Restart the service.
    sudo systemctl status mednafen: Check the status of the service.
    sudo systemctl enable mednafen: Enable the service to start on boot.
    sudo systemctl disable mednafen: Disable the service from starting on boot.

Please note that running the Mednafen service as the root user (User=root) may not be the most secure option. It's recommended to create a dedicated user for the service and adjust the permissions accordingly for improved security." (C) ChatGPT Turbo 3.5
