naomi 2

Hey All, I have a sega naomi filter board and buttons PSW1 and 2 (test and select) buttons are not working. Looking to replace them. I wanted to know if anyone knew what button would work as a direct drop in replacement. Thank you again. Tony

Hi everyone! I'd like to share NaomiDiag, a replacement diagnostic BIOS for Naomi and Naomi 2. I'm a contributor to the project, not the main author. Main features: • CPU, video and sound RAM tests, with chip-level fault reporting. • Results on screen, via serial and spoken aloud. • Cartridge...

Hello to all fellow arcade board users. My DIMM has 256MB of built-in memory and BIOS version 3.17. Yesterday, an additional 256MB stick I bought from an online shop arrived, so I installed it into memory slot 2. However, after inserting the new memory, the NAOMI system refused to boot up...

Edit- purchase pending Hey folks, I'm looking for a Naomi 2 motherboard. Prefer it on its own, but will consider bundles. Thanks in advance!

I've been slowly restoring an original US Monkey Ball, and I've hit a snag with the joystick... I could use some help, as I'm a full-fledged amateur. TL;DR the original joystick is drifting during gameplay and drifts different amounts as you play. I've tried calibrating it several times in the...

Hey Guys, Turned on my Naomi today and it was struggling to hold a stable picture. I tried it in 15 and 31 kHz but no difference. I tried a normal 15 kHz game and it was fine. Let me know what you think. Thank you. Video attached. https://files.fm/u/jn5ucapwrt

Hi everyone, I’m a newbie in the amazing world of arcade cabinets. I’ve recently purchased a full refurbished SEGA New Net City equipped with a SEGA NAOMI 2 + NetDimm Board and RaspberryPI3 with PiForce Tools. I’m able to successfully NetBoot both NAOMI and NAOMI 2 games by connecting with my...

Hi All, I have 9 CF programmed cards for a cf flash kit. Each card $12 USD per piece, or take all 9 for $90 USD. PayPal f and f. Shipping extra. Were working when last tested about a month ago.

Hi all, I've been troubleshooting a GD-Rom drive on my Naomi 2 board for the past couple days and i can't seem to get stuff working as it should, i feel like i've tried everything but no matter what i do, i get an Error 21 [The game is not acceptable by main board], which according to the...

Was inspired by this post: https://forum.arcadeotaku.com/viewtopic.php?t=23222 However, I’m referencing it here in hopes to get more details and have a better understanding of the issue. Just received a card reader and tried to get this working outside of an original cab. I saw an example of...

Hi there. I am looking to get my hands on a fully functional Naomi 2 system with the bios already updated to 4.02 multi bios, and the Chip 0-Key (although I don't think that's officially needed with the netdimm for home-booting) I'm pretty much looking for a turnkey system, I want to open the...

Hey all, I have a Initial D Ver 3 with one set of Naomi boards giving me trouble regularly so seeking a suitable replacement. If you have a spare Naomi 2 and able to help me out, please let me know. Cheers.

Hello everyone! This is a bit of a ride (no pun intended) so bare with me. I recently bought a Wild Riders cabinet off of Facebook Marketplace for very cheap. The owner said that it worked when he tested it but stopped working after transport and was just looking to get space back. But it...

Hi all, I've been reading to figure out how to get my VF4:FT disc working in my new Blast City and it's just so freaking confusing. A: Do I have to install a new power supply to use EITHER netboot or GD Roms? My cab has just a Jamma loom, no JVS. B: For the work/money I have to put in to get...

Been slowly testing this as I've had time over the past few months. I got the Naomi multiple years ago and the NetDIMM in presumably-working condition about a year ago. I didn't really start doing much testing until my Axunworks PSU appeared in the mail a few months ago. Setup Naomi 2 with...

Okay, if you've followed my repair log, you know that it worked for a while, then stopped for good when one of the BGAs crapped out. Well, I bit the bullet and bought another one from a questionable source, "guaranteed tested", for a fair price. It arrived yesterday and indeed, after setting...

I have a Naomi 2 that doesn't seem to recognise any Net-DIMM that I attach. I've got a few of them with various firmware versions; 2.06, 3.17, & 4.01, and none work. I was assuming it to be a fault on the DIMM itself (buffer chip?) until I've finally gotten hold of a second Naomi 2 and they all...

Can anyone tell me what this female connector is call or even better link me to one on mouser/digikey? I wanna make myself another of these cables but can't find it.

Does Ikaruga not support the Capcom IO? Is there another IO that I should be using instead? I feel like I've seen a website with IO compatibility before, but I can't for the life of me find it again.
