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). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Namco Galaga」の詳細全文を読む スポンサード リンク
