forgive my ignorance how do I start the roms of cps3 directly from retroarch?
following the guide I set the separate emulators and it seemed strange because many flatbacks that use retroarch as emulator I keep them together ... however I do not think that's the problem, I gladly accept the advice on the file .cfg I did not know that each core save the own configuration.
As soon as I have your suggestion, I'll try it tomorrow ...
I also tried the core fb_alpha_2012_neogeo as suggested by the tutorial but also the same result ... no rom starts.
