can anyone point me in the right direction on this?
i am curious 2 know hardware specs on the saturn and genesis
proc and memory type would be a bonus
alsanyone get slave zero running on a saturn emu yet?

SEGA SATURN ARCHITECTURE DESCRIPTION

A Bus
This data bus connects the CD-ROM and cartridge expansion to the central bus controller unit (SCU).

B Bus
This 16-bit bus runs at 28 MHz and connects the video and sound subsystems to the central bus controller unit (SCU).

VDP 1
The first Video Digital Processor (VDP) acts as the sprite processor. Because of the way the Sega Saturn handles 3D, not only does this chip calculate all of the sprites, but it also maps sprites into geometry. It relies on dual 256K frame buffers that handle rotation, and pulls data from a 512K texture RAM cache.

VDP2
The second VDP works as the background processor. This chip can generate up to five simultaneously active backgrounds, and can also rotate two playfields at once. It is also possible to have three normal scrolls at the same time as a field of rotation.

SCSP
This is the Sega Saturn's incredible sound processor. Easily the most potent piece of hardware inside the machine, it boasts 32 voices, FM synthesis, PCM synthesis, and 2 CPU interfaces. It features a full compliment of hardware, including a 16-bit 68EC000 at 11.3 MHz and a Yamaha FH1 processor for an overall frequency of 22.58 MHz. Other features include Direct Memory Access (DMA) for file transfer, a 16 channel digital mixer, and a 128 step digital signal processor.

Boot ROM
A massive 512K is taken up with the system's ROM. The Sega Saturn allows six different languages to be selected, viewing of CD+G discs, and a music CD option that allows the vocals to be removed from CD tracks.

SH2 CPU
The Sega Saturn contains two Hitachi SH2 RISC CPUs running at 28.6 MHz and 25 MIPS each. The SH2 is only two cm. square but it includes many important components that provide the chip with its power. By connecting both CPUs to the RAM, the SH2 can exchange data with memory directly, which reduces wait times. The SH2 also contains a 4K data cache that speeds up processing, and it has the ability to do involved mathematical functions such as multiplication and division in the CPU core.
