當然,國內很少見,因為當時的基板很貴,而且遊戲也很冷門。
我倒玩過一次,在12年前………………
我最近找到个资料,SEGA在M3跟NAOMI2之间的时期有发售过一个基板“HIKARU",参数CPU : 2 x Hitachi SH-4 128 bit RISC CPU with graphic functions @ 200 MHz 360 MIPS / 1.4 GFLOPS
Graphic Engine : Sega Custom 3D
Sound Engine : 2x ARM7 Yamaha AICA @ 45 MHz with internal 32-bit RISC CPU, 64 channel ADPCM
Main Memory : 64 Mbytes
Graphic Memory : 28 Mbytes
Sound Memory : 8 Mbytes
Media : ROM Board (max 352 MBytes)
Simultaneous Number of Colors : Approx. 16,770,000 (24bits)
Resolution : 24 KHz, 496x384, 31 KHz 640x480
Polygons : 2 Million polys a sec
Shading : Phong Shading
Lighting : Horizontal, Spot, 1024 lights per scene, 4 lights per polygon, 8 window surfaces.
Effects : (at least) Phong Shading, Fog, Depth Queueing, Stencil, Shadow, Motion blur
Others Capabilties : Bitmap Layer x 2, Calender, Dual Monitor (24 kHz)
Extensions : communication, 4 channel audio, PCI, MIDI, RS-232C

--------------------------------------------------------------------------------
Notes : This board was totally custom and very expensive to produce, it was only really designed for one game (Brave Fire Fighters) as it could do complex fire/water graphics.
There were eventually only 6 games made for this system beforce it was dropped in favour of the much cheaper Naomi 2.
It was also the first arcade board to be able to do phong shading.
是说这个基板可以做复杂的火焰跟水的图形处理?
看游戏图片色彩艳丽,跟M3一个类型,NAOMI2跟这个比实际画面就没有那么艳丽~~ |
