The Namco Pac-Man was an 8-bit arcade game system board, which was first used by Namco in 1980; the second and third games to run on it, ''Rally-X'' and ''New Rally-X'', were modified to support a larger color palette and scrolling. Three unauthorized ''Pac-Man'' sequels were later developed by Bally Midway, Namco's old US distributor, on this board between 1981 and 1983 - and after Namco ended their partnerships with them after the release of ''Pac-Land'' in 1984, they developed ''Jump Shot'' (a basketball simulation) and ''Shoot the Bull'' (a darts game) on it, in the following year. ==Namco Pac-Man specifications== *Main CPU: Zilog Z80 @ 3.072 MHz * *Instruction set: 8-bit & 16-bit instructions @ 460,000 instructions per second〔http://www.drolez.com/retro/〕 *Sound chip: Namco WSG (Waveform Sound Generator)〔http://system16.com/hardware.php?id=514〕 * *Sample-based synthesis: 3-channels of single-cycle wavetable-lookup synthesis, 4-bit waveform samples〔https://github.com/mamedev/mame/tree/master/src/emu/sound/namco.c〕 *GPU: Namco NVC293 video shifter〔http://web.archive.org/web/20130104063950/http://mamedev.org/source/src/mame/drivers/rallyx.c.html〕 *Video resolution: 224×288 (''Pac-Man'') or 288×224 (''Rally-X'' and ''New Rally-X'' have the monitor turned on its side) *Frame rate: 60.61 frames per second〔http://www.lomont.org/Software/Games/PacMan/PacmanEmulation.pdf〕 *ROM: 16 KB (''Pac-Man'',〔 ''Rally-X''〔), 22 KB (''Ali Baba and 40 Thieves''),〔https://github.com/mamedev/mame/tree/master/src/mame/drivers/pacman.c〕 32 KB (''Jungler'')〔 *RAM: 4 KB (''Pac-Man'') to 6 KB (''Rally-X'') * *Main RAM: 2 KB〔 * *Video RAM: 2 KB (''Pac-Man'')〔 to 4 KB (''Rally-X'')〔 *Color depth: 8-bit (256 colors),〔 9-bit (512 colors),〔 10-bit (1024 colors)〔https://web.archive.org/web/20130104201358/http://mamedev.org/source/src/mame/video/pacman.c.html〕 * *Colors on screen: 16 (''Pac-Man''),〔http://aarongiles.com/mamemem/part3.html〕 32 (''Pengo''),〔 64 (''Rally-X'')〔 *Graphical planes: * *Sprite layer: 8 sprites on screen, 64 sprites in memory, 16×16 pixels size,〔http://books.google.co.uk/books?id=DqePfdz_x6gC&pg=PA70〕 4 colors per sprite,〔 sprite flipping〔 * *Tilemap background: 8×8 tiles,〔 4 colors per tile,〔 scrolling (''Rally-X'')〔 * *Radar tilemap (''Rally-X'')〔 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 Pac-Man」の詳細全文を読む スポンサード リンク
