programmers have produced some of the most engaging experiences in the history of interactive media ... Unshackled by a struggling console platform, this platoon of world-class software developers can do what they do best for any machine on the market." Game Informer, commenting on Sega's tendency to produce under-appreciated cult classics, wrote: "Let us rejoice in the fact that Sega is making games equally among the current console crop, so that history will not repeat itself." Technical specifications Hardware The Dreamcast measures and weighs . Its main CPU is a two-way 360 MIPS superscalar Hitachi SH-4 32-bit RISC, clocked at 200MHz with an 8 kB instruction cache and 16 kB data cache and a 128-bit graphics-oriented floating-point unit delivering 1.4 GFLOPS. Its 100 MHz NEC PowerVR2 rendering engine, integrated with the ASIC, can draw more than 3 million polygons per second and use deferred shading. Sega estimated the Dreamcast's theoretical rendering capability at 7 million raw polygons per second, or 6 million with textures and lighting, but noted that "game logic and physics reduce peak graphic performance". Graphical hardware effects include trilinear filtering, gouraud shading, z-buffering, spatial anti-aliasing, per-pixel translucency sorting and bump mapping. The Dreamcast can output approximately 16.77 million colors simultaneously and displays interlaced or progressive scan video at 640 × 480 video resolution. Its 67 MHz Yamaha AICA sound processor, with a 32-bit ARM7 RISC CPU core, can generate 64 voices with PCM or ADPCM, providing ten times the performance of the Saturn's sound system. The Dreamcast has 16 MB main RAM, along with an additional 8 MB of RAM for graphic textures and 2 MB of RAM for sound. It reads media using a 12× speed Yamaha GD-ROM drive. In addition to Windows CE, the Dreamcast supports several Sega and middleware application programming interfaces. The Dreamcast can supply video through several accessories. It came with A/V cables, at the time the standard for video and audio connectivity. Sega and various third parties also manufactured RF modulator connectors and S-Video cables. A VGA adapter allows Dreamcast to connect on computer displays or enhanced-definition television sets in 480p. Models Sega constructed numerous Dreamcast models, most of which were exclusive to Japan. The R7, a refurbished Dreamcast, was originally used as a network console in Japanese pachinko parlors. Another model, the Divers 2000 CX-1, is shaped similarly to Sonic's head and includes a television and software for teleconferencing. A
