- [Instructor] Now here comes the fun part, playing games. Launching a properly loaded ROM in retropie is easy. Just navigate to appropriate system in EmulationStation, choose a game you want to play and press start. For most games, you don't need to do anything more than that. But let's take a look at what's happening behind the scenes, when you launch a game. Retropi uses a piece of software called Runcommand that allows games to be launched from the command line. And all EmulationStation does when launching a game, is to invoke Runcommand to launch the chosen emulator and ROM. The see exactly what that command is you can navigate to the /opt/retropie/configs directory, and then to the directory of your emulator. I'm using mame-lib retro, so I'll navigate there. And I'll cat the emulators.cfg file. You can see the emulator name as well as the path and the options that Runcommand we use to run the emulator. It also shows the default emulator in case you have more than one installed…
