Display running game on LED Matrix - Help



  • Hi

    I am fairly new to all this RetroPi and Linux in general.

    What I seek is a hint in the right direction, "Is this doable and how do I do it?"

    I have finished my full size Arcade Machine, and the software is up and running fine.
    I got a 32x128 LED Matrix displays that I intend to use as marquee to display custom images based on what game is running using - hzeller/rpi-rgb-led-matrix from Github.

    I have seen this when googling the topic, but none have detailed on how to.

    I see when using the PS command that eg. Bubblem.zip is running in /retropi/roms/arcade/
    but I need help on a script that runs and checks what game is currently running and then displaying a picture.

    I know someone did something similar for changing button lights depending on what emulator was running, and was thinking something similar could be used.

    And help or push in the right direction is appreciated.

    Regards
    Christian

    If you're using RetroPie, then you can run your scripts when starting/ending a ROM with Runcommand support for onstart/onend scripts - https://retropie.org.uk/docs/Runcommand/#runcommand-onstart-and-runcommand-onend-scripts. The scripts receive some parameters so you can determine which emulator and game you're starting/finishing and run the appropriate actions/scripts to control your display.



  • you could try this project http://pixelcade.org , includes artwork for 128x32 too. Disclosure, I'm the creator of this one and sell them as kits.
