    I've got a cartridge based Sega NAOMI on it's way to me with Dead or Alive 2 Millennium Edition, so I was wondering would it be possible to get this hooked up to a HD TV via HDMI or component (D Terminal)? Also what sort of PSU do they need and is it possible to use a USB controller on them such as the 360 controller or USB Saturn pad? I guess it is via some sort of connection kit since I've seen normal retail Saturn pads used with NAOMI arcade systems here in Japan.

    Thanks!

    HDMI ?
    LOL
    naomi can only output low or mid arcade res, so the max resolution you are going to get from it is 640x480
    the board is going to look like shit on lcd displays ...
    To power it, you can get a regular atx psu and make an adatpor, or get an original psu from yahoo (cheap and less problems)

    you are also going to need a jvs io board, there are many different models out there, just choose the one that better fits your need

    To clarify this last point, controlls on naomi go over an usb connector, but its not usb protocol, they just use the same conector and cables, but protocol is rs485 instead USB. So forget about get an adaptor to usb or use usb pads, you need an jvs io board

    NOAMI outputs VGA, it's what I use for mine direct to my monitor.

    And the VGA output will not "look like shit" on a LCD display. It will look as good as any device outputting VGA at 640x480. Pretty much like your DreamCast running using VGA.

    Low, Medium and High resolution tend to be linked to the video frequency, low is 15Khz, Medium is 22Khz and High is 31Khz (roughly). The Naomi will do a 640x480 which is deemed high resolution and the naomi outputs either low or high resolution.

    The Naomi will output a VGA signal, however as it's slightly off, you may find that LCD TV or monitor won't lock onto it.

    You will need a sega or capcom (prefered) IO board to hook up a Supergun to the Naomi, these aren't too hard to find mak-jp do them for around 6000 to 10000 yen. The capcom I/O and most of the Sega I/Os will power the Naomi via the JAMMA interface so you won't need to get a full blown naomi PSU (unless you want to use GD-ROMs etc then you probably will need one...).

    Mak will happily sell you a supergun modified to work happily with the naomi too, but it's going to get expensive quickly.

    Just to itterate what a few said.

    You will need the following
    1. Sega JVS IO PCB
    2. JVS Digital Harness
    3. JVS PSU (makes things really simple)
    4. Possibly some upres hw like a XRGB

    Not all LCDs support the low res requires by early JVS HW at 31khz. So if you have something like an XRGB you should be set on that front.

    For power I simply would just buy a JVS PSU and rewire the AC plug so you can just plug it into a local outlet

    For Input, sadly you will need a full on JVS IO board. They're actually pretty easy to wire. You only need to wire 2 main parts. 1) a +5v Input 2) Joystick to a Digital Harness.

    I did exactly what you're waning a few months ago so I could play Namco System 246/256 games on my PC monitor. Here is how mine turned out.

    The whole process might seem complicated but surprisingly it's actually really really really easy to build.

    my naomi board must be different than yours, or you never put it into a decent crt display

    Any 2d naomi game will look worst than shit on LCD and most 3d games do look as shit aswell, remember, its 640x480, not even 800x600
    those games look horrible into lcds (if you are lucky and yours can handle it at all)

    It boils down on how your monitor turns an SD resolution to its native pixel resolution, which means that quality depends on the scaling capabilities of your TV - provided you can get it to sync to the refresh rate it needs to be fed.

    It really depends on the quality of the LCD and it's internal scaler (as it's most likely upscaling the input to something it can handle).

    I think my greater concern with using an LCD over CRT is lag but most new LCD have a pretty high refresh rate (specially if it's a PC LCD).

    I'd actually love to see what a Naomi/System246 would look like on a Plasma. Tekken 5 has a few levels with really good color contrast which look stunning even on my LCD.

    Thanks for all the info, guys. Lots to read up on but yes, it seems I'll need to sort out a JVS Power unit and control interface. I've seen those on Yahoo Auctions. I don't think I'll need any XRGB box since my Dreamcast looks amazing on my Mitsubishi TFT that I use for the PC and very nice on my Toshiba LED TV. I would have thought the NAOMI would look just the same since they are basically the same hardware.

    Anyway, thanks for the info. It maybe a month or two before I get it up and running wigh cash being a bit tight at the moment but I'll let you know how it goes. Hey, if I'm lucky it may come with the JVS stuff. All I was told is that it has been tested and fully works.

    Just FYI but you should be able to put together the JVS IO & PSU for less then $100 if you shop right.

    Then after that it's either buying a controller to mod or an arcade stick to mod. I reused some old pelican controller I had in the closet and some happs buttons from a mod project a friend gave for me to do but changed his mind and let me keep it.

    I'm not going to be really helpful but would you mind posting some pics once you get the thing up and running? I'm a big DOA fan and would love to see some pics of a DOA2M copy running.

    Honestly it would be exciting to see some footage of doa2m running, anyone know if there is any console port based on it? Also yakumo now that you have a naomi board coming, be on the look out for dynamite deka ex, that never got a console release.

    I'll a video once I get it up and running. I don't think I've ever seen Dead or Alive 2 Mil' edition running myself. Will be nice to see what's different from the regular release.

    sayin999, yep I was thinking about Dynamite Deka ex. I can imagine that's expensive though since it's one of the newer NAOMI carts. I'm only going to be buying none Dreamcast releases for it anyway so it will appear in my collection at some point in time.

    I saw DOA2 Millennium in an arcade in Florida some years back. I actually played that game before I ever played the Dreamcast version. I was kinda disappointed when I saw the Dreamcast version because there seemed to be fewer polygons and fewer effects. I don't know if this is actually the case or if it had something to do with playing on an arcade monitor vs. over composite. I've never seen the two playing side by side so it's hard to say.

    The Naomi arrived today. It stinks of tobacco but that's to be expected considering it's been in an arcade cab. I'll have to air it out. It's also pretty dirty so a good clean is in order but since I didn't pay for it I can't really complain. My wife bought it as an early birthday present.

    If I'm not mistaking, those black boxes are digital audio outputs, right? Or one out and one in? It also seems to have a VGA port so I'm guessing connection to a VGA monitor is possible with a direct cable. I've seen Naomi systems on flat screens in arcades here so .....

    er no, the toslink connectors are for communications one for transmitting data and one to receive data (hence the TX and RX). There is a VGA port, two audio jacks (these are unamplified), however you aren't going to be able to do much with it with out an I/O board, well you could buy a PSU and watch it running.
