A question that has been bothering me for some time, I have a collection of MARIO from different emulators, now I wonder how I can make them open correctly in retroarch automatically and have the right core for that game that I'm going to launch?
I know how to do it for a single emulator and insert the core, but for one or more cores how to do it
"[romfilename]" -L cores/nestopia_libretro.dll
