Bugs:
  • The backround sound during gameplay is slow by about a factor of 2. The backround sound during gameplay is slow by about a factor of 2. I have 3 original midway boards and the backround beat on those all match exactly so I'm sure it's just a problem in mame. If I run a board right next to my mame cab - the background beat in mame sounds at almost exactly 1/2 of the correct pace. The rest of the sounds and the gameplay itself all appear perfect. It's only the backround sound that isn't correct. mp3s from PCB are attached. Follow-up by Tafoid in 0.116: The earliest I could test was MAME 0.37b15 - bug still exists then. dropdeadhippie (ID 00443)
