Naomi
what exactly is a Naomi board? I know what it is, but how exactly it works? it has some kind of disk player? the games aren't contained directly on the board chipset? I ask this because searching the web I'm stepped into a "Naomi GD-Rom", so I was wondering if Naomi games are just GD-Roms and all Naomi boards are the same, and just the disk changes...

As far as I know there are different Naomi systems, some with and some without GD-Rom. System 16 has some info on them (with pics). -
Naomi games originally existed on Naomi ROM cartridges that plugged into the Naomi motherboard.Of course the cartridges proved expensive for operators to purchase , and with the decline of the arcade industry in Japan this hampered sales.
Luckily Sega always planned to release games on a proprietry disc format.Gigabyte Rom -discs (GD-roms ).This not only saved Sega saved some finances but also saved the operators a lot of cash.We'll that was the plan , a lot of operators I knew shutdown.
( Not sure if thats answered your question or not ^^*)

Naomi ROMS + GD-ROMS.
(I've had 20+ Naomi systems and 5+ Noami'2 systems over my time , for my personal collection and some were imported for friends.Sadly another part of an old collection now all gone, with a lot of pics too ^^
off topic ,VF2 never did get this up and running

thanks. wonderful collection, ExpertKing!
looking at your pics, I wonder if... it's possible to link the Naomi to a TV Color?Comment

Yeah no problem for standard resolution games , use a standard supergun setup and as well as a Jamma I/O for the Naomi setup and you should be fine.
Ideally you would use the VGA output on the Naomi motherboard and a multisync monitor.Comment

You can't run a GD ROM safely off a supergun though. You need a 3.3v line. Naomi is natively JVS, not JAMMA.Comment

No thats true , although you can run one from a Naomi 2 board apparently. Personally I always purchased a separate PSU for any Naomi GD-rom setup, as in the pic above.
hence the I/ONaomi is natively JVS, not JAMMA.Comment

You can run a GD ROM in a JAMMA cab with a Naomi 2 mobo and the 5V cranked way up but it's something I'd never do as its bound to fudge your I/O over time (and kill any JAMMA board if you forget to turn it down ). Superguns rarely have adjustable voltage or enough juice on the 5V. A seperate shuttle type PSU is definitely the way to go.

Being JVS, Naomi is one of the most daunting home arcade formats but it aint half worth it when you have Final Tuned, Ikaruga and MVC2 running at home 8)Comment
