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)

- TRIVIA -

Considered as a a hack of "Galaxian", this game seems more like a hack of "Moon Alien" by Nichibutsu, but with the graphics changed to look more like "Galaxian". This explains why the shots move with the ship and why the fuel gauge is there. Galaxian also didn't use a 'title screen' formed with graphics, it went straight through to 'We are the Galaxians'. Also, the rate of fire is much faster and the alien's movements are more random.
