I'm trying to set up RetroArch and I have been following the tutorial (1) up to about 5:20 when it goes "associated platforms." I want to emulate PlayStation 1 games but the emulator "Beetle PSX HW" doesn't seem to be on the list of associated platforms.
I tried adding a platform by adding "Playstation 1" under [Associated Platfroms] and choosing the file in the Cores folder for [Core] but I don't know what the [Extra Command-Line Parameters] are supposed to be. I assume the [Default Emulator] box should be checked although I hear different PS emulators have different advantages for different games so I might want more than one. Also what is M3U and do I want to check it?
