Galaxian (Namco set 1)

0.15 [Nicola Salmoria]

0.05 [Nicola Salmoria, Robert Anschuetz]


- 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 (see mp3s of the PCB). galaxian0103u3gre dropdeadhippie

Possible Bugs:

- Clone batman2: A little bit of red and yellow garbled graphics appear in the lower left corner of the screen, and yellow and purple garbled graphics sometimes flash above it on and off during gameplay. batman237b16gre Smitdogg

The dip switch menu might display wrong settings. Compiled from information provided by friends and Uncles on RGVAC. Some info on Galaxians taken from Arcade Emulator by Robert Anschuetz.
