Ola chaps. In the near future I'm looking to pick up a Sega Naomi, but I'm looking to get up and running with less than the standard bare essentials if it is at all possible. Ideally I'd just buy a net city to save time, but I can't afford that just yet so I'm intending to consolise a Naomi for home use. I should point out I'm not bothered about Naomi GD games. I'll use my Naomi GD unit that has been kicking around my room for some time as and when I get a Naomi 2 (colour coordinated ) which effecively limits me to 2 or 3 playable Naomi cart games only, until I get an I/O and control panel that is. As far as I understand it I can just use the VGA output straight to my TV and I won't need a sound amplifier as I can just take a lineout from the Naomi into the line in on my TV too. As I have a Coolermaster GX 550 PSU going spare I can put that to good use using a Naomi to ATX adapter too. Anyhow to my main point. I believe there is a controller setting which must be set to capcom and only VMS-kit games will work to make use of the Dreamcast controller. If the seller uses their gubbins to set the BIOS up as desired and then ships the Naomi to me, could I play the handful of Dreamcast controller supported games out of the box with no JVS / Campcom I/O? Obviously I'd need to hack an extension cable to play my games on the Naomi too but the pinout for that is freely available.
I'm no expert but as far as I know there isn't a way of connecting controllers from a Naomi without some kind of JVS I/O device. I use the Capcom one wired to a Jamma Harness using Neo Geo sticks. If you need one PM me as I have a Sega IO board gathering dust.
The Naomi is basically a Dreamcast with more RAM & VRAM and as such it has a maple bus. The Dreamcast controllers use the maple bus on Naomi CN6 & CN7. I dont think the Dreamcast controllers can edit the bios settings to use the capcom controller style though as the controllers do not work until the capcom mode is enabled, hence why I'm wondering if it would work if the seller changed the setting using their I/O and then I could think happy thoughts on the cheap
Ask Yak as he was able to make a setup based on info I gave Basicly you need 1. A Naomi MB 2. A Sega JVS IO (The Actual JVS IO not JVS->Jamma but those work) w/ harness 3. A Sun JVS PSU 4. A Controller to wire 5. A decent Monitor (some LCD monitors have problems with an arcade 31khz signal) 1. Just do some light wiring to make the JVS PSU run with a standard outlet plug 2. Wire some form of a +5v power line to the JVS IO 3. Wire the controller into the JVS Harness (will have to find the pinout again, give me a few days) 4. Plug it up and you're good to go. I have a cheap JVS rig build that I use for some of my arcade stuff since my Cab is at work. It's much easier to build then you think.
Great thread! this is something I intend to do at some point too, I had asked elsewhere but received little info
Is there any chance someone could disconnect their I/O and try to boot a game and see if this is the case? I'm trying to avoid spending money I don't need to. Obviously I'll add an I/O at a later date I just want a running set up as quickly and as cheaply as humanly possible, even if it only works with 3 or so capcom VMS-kit games. As for the Sun PSU I'd never say never, but it would be cheaper for me to get an adapter for my spare ATX PSU than it is to buy a dedicated JVS PSU.
"This video is private"... is that something like: "This video is not available in your country"? It wouldn't make sense for someone to post a private video in a forum if no one can watch it.
On most modern arcade games (IE Post JVS2 standard), they will not boot with out an IO. You'll get an IO Error or blank screen.
Arf ok cheaping on the initials et up ver 2. All of the above such as having the Naomi seller set the cotnrol style to capcom, then using the Sega JVS I/O (which is cheap compared to Capcom and Sega ver 2) have it plugged in for arguments sake so the game should boot, but then have no sticks etc plugged into the I/O (just usb lead / power) and use the maple bus for Dreamcast controller on CN6 & 7. Will that work, or would I still need to go the whole hog, fake a coin mech and control panel?
I just picked up a Naomi myself... The plan is to make a Sega JVS I/O type 1 to JAMMA adapter using a fingerboard, and then use a supergun for digital controls, coin, etc. The reason I would like to make a JAMMA adapter myself, instead of just getting a standard Sega or Capcom JAMMA adapter, is that AFAIU the standard Sega/Capcom JAMMA adapters don't work with driving games such as Initial D and Crazy Taxi. Even though i.e. the Sega JAMMA adapters have the 26 pin analog I/O connector needed for the wheel and pedal pots, it is my understand there are compatibility issues with the games (?).
Should be enough but make sure a game is compatible with the DC plugged into CN6 & 7 (i think it was only in a few games?). You can get a sega JVS IO or sega Jamma IO for dirt cheap. Then you simply can just wire a controller up with out buying anything else. There is a UK seller who has Sega JVS IO for $40 each. -edit- Here are some cheap ones on ebay. http://www.ebay.com/itm/SEGA-I-O-IN...447?pt=LH_DefaultDomain_0&hash=item20c9ba2687 http://www.ebay.com/itm/I-O-Interfa...063?pt=LH_DefaultDomain_0&hash=item51a0dd0817 http://www.ebay.com/itm/SEGA-HITMAK...474?pt=LH_DefaultDomain_0&hash=item27ca8657ca
I have a sega i/o board you can have for postage(UK based) if you still need one? I had a cab now got a jvs supergun so have some parts spare
Wow thats very kind of you but I wouldn't want to impose. I actually listed my GD-ROM unit for sale now, which isnt the end of the world as I could still play cart based games anyway as and when I buy the other kit. The problem is I have a tight budget and a couple of big purchases to make before then (full Sanwa mod on Dreamcast arcade stick to repair it after it got broken bny friends/family and a nice expensive dreamcast item). Even for just a cart only system it could take me 8-16 weeks to get started
No problem if you every need it i can ship it i stripped the cab down so have alot of spares and i no longer need them
I have I/O if you want, I can also make cable that has each button wired and you can connect them to whatever you want via soldering or whatever you prefer.
