Chankast and Naomi 2 or 3

[Shakaru]

Well I noticed on the main page the pictures of Naomi software running just fine, but I was woundering if Naomi 2 and 3 were able to play eventually on Chankast. Also, if other sega systems like Model 3 were going to be able to run or if there are other emulators that run theses boards?

[PsyMan]

Any Dreamcast based boards can be emulated by Chankast (in theory) but note that NAOMY 2 has more memory than NAOMI and NAOMI 3 has a different (more powerfull) graphics chipset.

Model 3 is a different hardware from Naomi or Naomi 2. There is already a Model3 emulator in development. It's not released yet though.

@fivefeet8: They are mentioning Naomi and not model3

I only hope that moedel3 will be worked out better then model2 emulation.... The Emulator is far from ready(Chankast is in a much further state compared to model2 emulation) but hasn't shown any improvement the last 8 months

The original poster asked if model 3 ran in Chankast. I responded to that.

DOH *slaps forehead*

[life_247]

whats the model 3 emu called, sounds interesting.

Naomi 3 is very different, naomi isnt all that similar to dreamcast anyway.

P.S source info: cyrus_64 ;-)

I agree on NAOMI 3 but not 1 and 2

NAOMI 1

HARDWARE DESCRIPTION - DREAMCAST BASED
CPU : Hitachi SH-4 64-bit RISC CPU (200 MHz 360 MIPS / 1.4 GFLOPS)
Graphic Engine : PowerVR 2 (PVR2DC)
Sound Engine : ARM7 Yamaha AICA 45 MHZ (with internal 32-bit RISC CPU, 64 channel ADPCM)
Main Ram : 32 megs
Main Memory : 32 MByte
Graphic Memory : 16 MByte
Sound Memory : 8 MByte
Media : ROM Board (maximum size of 172MBytes) / GD-Rom
Simultaneous Number of Colors : Approx. 16,770,000 (24bits)
Polygons : 2.5 Million polys/sec
Rendering Speed : 500 M pixel/sec
Additional Features : Bump Mapping, Fog, Alpha-Bending (transparency), Mip Mapping (polygon-texture auto switch), Tri-Linear Filtering, Anti-Aliasing, Environment Mapping, and Specular Effect.
Known games on Naomi hardware : 56+

NAOMI (New Arcade Operation Machine Idea) also Japanese for beauty above all else.
Notice that Naomi has twice the amount of main memory and graphics memory that Dreamcast has, so ports from Naomi to Dreamcast may involve more conversion time. Also note that the Naomi board has four times the sound memory of the Dreamcast, and the reason for this is because the Naomi board is'nt meant to spool redbook audio from the GD-ROM drive.

The Naomi architecture is very flexible in that a cabinet can have anywhere from 1 to 16 boards. A multi board system would operate in parallel increasing the power of the system tremendously! Theoritically a 16 board Naomi system could do (16 x 3.5 mpps) = 56 million polygons per second maximum! Realistically it would most likely be around 20 to 30 mpps. Then of course there is also the issue of the CPU being capable of driving all of this hardware.

======================================== =================

The NAOMI 2 (New Arcade Operation Machine Idea) also Japanese for beauty above all else.
CPU : SH-4 128-bit RISC CPU (200 MHz 360 MIPS / 1.4 GFLOPS)
Graphic Engine : 2 x PowerVR 2 (PVR2DC-CLX2) GPU's - (under the fans)
Geometry Processor : Custom Videologic T+L chip "Elan" (100mhz) - (Under Heatsink)
Sound Engine : ARM7 Yamaha AICA 45 MHZ (with internal 32-bit RISC CPU, 64 channel ADPCM)
Main Memory : 32 MByte 100Mhz SDRAM
Graphic Memory : 32 MByte
Model Data Memory : 32MByte
Sound Memory : 8 MByte
Media : ROM Board / GD-Rom
Simultaneous Number of Colors : Approx. 16,770,000 (24bits)
Polygons : 10 Million polys/sec with 6 light sources
Rendering Speed : 2000 Mpixels/sec (unrealistic max, assumes overdraw of 10x which nothing uses)
Additional Features : Bump Mapping, Multiple Fog Modes, 8-bit Alpha Blending (256 levels of transparency), Mip Mapping (polygon-texture auto switch), Tri-Linear Filtering, Super Sampling for Full Scene Anti-Aliasing, Environment Mapping, and Specular Effect.
Compatibility : Fully backwards compatible with all Naomi and GD-Rom games.

Notes : Notice that Naomi 2 has four time the amount of main memory and graphics memory that Dreamcast has, and twice that of the naomi so ports from Naomi to Dreamcast may involve more conversion time and a great loss of texture detail. Also note that the Naomi2 board has four times the sound memory of the Dreamcast, and the reason for this is because the Naomi board is'nt meant to spool redbook audio from the GD-ROM drive.

Show off... :P


I only hope that moedel3 will be worked out better then model2 emulation.... The Emulator is far from ready(Chankast is in a much further state compared to model2 emulation) but hasn't shown any improvement the last 8 months
Hope to see any improvements in the next time, but if he's now working on Chankast, so he won't have time I think.

[alcoatjez]

whats the model 3 emu called, sounds interesting.

It's called Supermodel. Info can be foundhere (http://www.system16.com/model3/).

Well Chankast is a higher priority for me ;)... But boy would I like to see Daytona and virtua fighter 2as it was in the arcades :)

Ask me!!!
BTW: YOu didn't say anything to the show of thing? :P

[Heinster]

lol, as alcoatjez pointed out already it was info gained very ez by going to the system16 site ;)

Euh... And ask what?

[MasterPhW]

Euh... And ask what?
How it would be for me, to see these two games (and more9 look alike in the arcade and run in a normal speed.
