I’m running an Rpi3 at home with RetroPie, which plays a ton of emulated classic games. I’d like to be able to read the system process, and tell either what system is being emulated, or what specific game is being played.
For example, when playing a PS1 game, I get this output from ps aux on the Rpi:

My original thought was to check for the emulated system with something like ps aux | grep roms/psx, which will return any lines containing roms/psx, which is the folder where the game file resides.
I also have Glances already setup on the Rpi for system info. Would there be a way to use this instead?
