Hi Maybe anyone can help. I have download a mame Romset 0.222 and have insert it in Launchbox. The Emulator is Mame64 0.222. The Emulation is slowly and the sound has an echo. When i start Mame64 directly it is the same. When i start the Rom with Retroarch the emulation is ok. I have the problem with all Roms i have started. I have try it with Kung Fu Master. The Laptop is a 2018er MacBook Pro with WIndows on it.
