I recently bought a 4 slot Neo Geo MVS the sounds works great once I add a credit and get into the game play but during demo mode it never makes a sound at all. How can I fix this? Hope you can help thanks!

@aceadams7979 sounds like you "attract sound" option is turned off. you should be able to access from the test switch behind the coin mech, or if you have/ or get a custom bios you can do it on screen.
