Namco Galaga

This article is a generic description of Namco's 8-bit "Galaga" hardware. For the specific arcade game, see Galaga.

The Namco Galaga is an 8-bit arcade game system board which was first used by Namco in 1981; the fourth and fifth titles to use it, Xevious and its 1984 update Super Xevious, were also modified to support a 129-color palette.

Namco Galaga specifications

• Main, graphics and sound CPU: three Zilog Z80 microprocessors, 3.072 MHz
• Sound chip: Uses the same custom three-channel WSG (Waveform Sound Generator) as the Namco Pac-Man hardware.
• Other chips: Custom input/output controller (type 1) which handles the controls. Bosconian also has a second input/output controller (type 1) which handles the speech (from a Namco 54XX DAC).
• Video resolution: 224 x 288 (Bosconian, like Rally-X and New Rally-X, has the monitor in a landscape orientation. The other games are portrait.)
• Notes: Each of the five games uses a different video board (except Xevious and Super Xevious, which use the same one).
