naomi

Recently got a Sega Net City, along with a Naomi GPU. It boots up and runs the game, but wont take any inputs, not even the "test" or service buttons. The I/O board is a Sega 837-13551 I've made sure everything is powered, and double checked that pins 1 and 3 are connected on the 60 pin...

I’ve recently bought an Impress and old Astro City I’m waiting for delivery on. And wondering what I’m going to need to install my Netboot Naomi in them, I have a Capcom IO board but I know from testing in my Blast that the Capcom IO board can’t support the netdimm but I have the JVS power...

Hey everyone, This is BattleLounge from Portland, OR. I've been collecting/restoring arcades for 3 years now. I usually lurk other forums for repair/troubleshooting help and decided to start socializing here. My main interest is fighting games. I'm not a technician or specialist but I've...

So I finally have everything bought sorted and tested to start my Naomi project cab. I was thinking about doing a LCD select screen but then I read about Pi force web. I'm still processing all the documentation but has anyone successfully set this up and have any pointers...

Hi Everyone, First of all, a BIG thanks to all that help this site grow. This site has helped a grown kid/man fulfill his arcade dreams. Okay, let's get to business. The Naomi Question: Does anyone know if a Dreamcast Lightgun will work with a Naomi for House of the Dead 2 and other lightgun...

Up for trade I have 2x Outtrigger panels, with carts and comm boards. I hate when people say "rare" but these are indeed rare. I've repaired the joystick and trackball housing on one of the panels. For the repair, as well as pics/video, see...

Need some help on wiring up the power on a 837-13551 I/o board. What pins do I use for power? CN7 or CN3? I can't figure it out from the old harness, it appears that the CN7 has run directly to the power supply with 2 5v and 2 grounds. Thanks for the help!!

Hi, my upscaler thingy aims to be as compatible with naomi setups as possible. Do anyone here have a scope and a Naomi handy, and can check if hsync/vsync is TTL/5V? Would do it myself, but away from my toys for a few more weeks.

I recently purchased a cheap type 1 i/o board that had a badly burnt up 12v input header. I was happy to discover it works fine without 12v. I had assumed I'd be missing out on lamp outputs, but never tested. Today, in my OR2SP cab that has a fully working type 1, I noticed I didn't have the...

I'm just kind of thinking out loud with this idea. I don't know when I'll take time to dig into it. I currently own an OutRun 2 Special Tours driving cabinet and have both the Chihiro and NAOMI 2 for loading up several different driving games. OutRun2 (Chihiro) and Initial D (NAOMI 2) utilize...

I have a netdimm that I had purchased on ebay ages ago. It netboots just fine and is currently updated to the latest firmware 4.02. The only problem is when the jumpers are switched to GD-Rom mode I only get a black screen and no boot at all. I know there is nothing wrong with the Naomi 2 as I...

Are all Naomi games compatible with every Naomi i/o board? About to build up a new Naomi setup and trying to choose an i/o board, but want to make sure I choose the right one.

Making tests with my netdimm for upgrade it to the firmware 4.02. I discovered one thing, with the firmware 2.13 i can send games with GameTransfer.exe and that games work fine. I completed these games, from the beginning to the end, without freezing, and without resets on the board. Street...

I'm JVS modding a Mad Catz MC2 Racing Wheel (Xbox original version) so that it can hook to the Naomi and Chihiro to use with those racing games. I'm running into a problem with the Gas Pedal... it'll work, but it only ever goes at a slow speed and won't ever really give it the gas and drive...

Hey there, I came here because I am working on my naomi2. I have worked on other arcade systems before and have been restoring and selling locally but I dont know anything about super guns or consolizing, which is my intention now. I hope to get some education from some of the older and wiser...
