Execute Python Script at ROM Startup

[silviustro]

Hi everyone.

So, I had an idea to display the console that is being currently emulated using an RGB LED or an LCD screen. In order to do that I would need to write a python script to control the GPIO pins.

This is my question: How do I execute the script every time a ROM gets loaded trough EmulationStation?

I was thinking maybe adding a new parameter to the "es_systems.cfg" file with the location of the script, but how would I execute it?

Thanks in advance for the help (;

As mentioned on Reddit, runcommand supports user_script "runcommand-onstart.sh" for exactly this.

Thanks for your answer! I will have to try it out.

Once you get it working, please let us know how you did it. I was thinking of displaying the name of the game, or better yet, game art while the game is being played on a GPIO-driven screen.

Here's an awesome bartop with an animated secondary display that inspired me to look into this a few months ago. I just re-found the post on reddit
