The following emulators doesn't work: N64, sega32x & NeoGeo System: 4.0 beta 3 - The same also for V4 beta 2 Also all Bios-ROMs are installed with verified checksum check behavior: Tried round about 50 different games with the same result. After starting the screen get´s black for 5 seconds. After that I come back to the Main menu. I also tried to change the emulator settings to select other cores. But without an effect.
