Launch a game directly when entering retrobat

My goal is to launch a game directly through a .bat file when I boot up the PC
But to do this I need to know how to write a command line that allows me to do this.
Does anyone know if this is possible?
Thanks in advance

Retrieves the command generated by retrobat for the desired game from emulatorlauncher.log

But retrobat won't be a background task. You can, for example, add another command to your batch running the game, which will run retrobat if the game is closed.

HELLO

You can make RetroBat start when computer starts.
You can select a game to appear at RetroBat start.

All other way of doing is out of the RetroBat support.
