Guys... If I adjust the screen refresh rate slider in mame, will it give me the correct video game speed and correct audio (example mortal kombat 2 54Hz on 60Hz screen)? Mortal Kombat 2 runs too fast on my 60 hz android phone but when I adjust the screen refresh rate slider to 60Hz the audio slows down correctly but I'm not sure about the gameplay speed (but it is smoothly scrolling). I am using this in retroarch on android so that is probably how the audio is being corrected but not sure about the game play speed/smoothness. Any help?
