Your videos are so amazing my man ❤️ I was born and raised into the arcades and still am❤️ and the Naomi is hands down one of my all time favorite sega arcade hardware, of course you have tones of other sega arcade hardware like the model 1,2 and 3 and the sega ring edge 1 and 2 but Naomi has always spoken to me the most and I think that’s because SEGA the god sents of the arcade scene ❤️ has achieved there first and only arcade perfect home system, AKA the sega dreamcast ❤️ Over the years sega as always been trying to do / achieve what SNK had achieved with literally turning there arcade hardware the neo geo MVS into a IDENTICAL home system called the AES, so once that happened, sega was always trying to turn its home systems into a system that could match the power of its arcade boards that were out at the time, Like for example, the genesis was supposed to have the power and capability’s of running games arcade perfectly from segas system 16 arcade board, then when the sega 32X came out they were trying to have that he an arcade perfect replica of the sega model 1 arcade board to have in the home and then the sega Saturn was suppose to be a arcade perfect home version of the sega model 2 arcade board but they all came pretty close but no perfect dice 🎲 So sega finally got there cards right and learned from all there mistakes and there wrongs and finally built a home system along side the sega naomi at the time so that way they could just use the EXACT SAME full sega Naomi arcade board and just put a sega dreamcast shell around it And since the sega dreamcast was using the exact same GD rom discs as the sega Naomi the sega Naomi arcade games to dreamcast home ports would be converted so easily And effortlessly thus having an end result of a 💯% sega Naomi arcade perfect conversion at your home ❤️ And the Japanese exclusive sega dreamcast arcade stick used the EXACT SAME buttons and lollipop joystick as the ones used on sega arcade candy cabs seen in arcades in Tokyo and all across Japan 🇯🇵 ❤️
@@AllAboutTKK anytime my man ❤️ Ya see when sega was building its new dreamcast system in 1999 they thought the only way to achieve arcade perfection at the home is To literally just home consolize there sega Naomi arcade board, like how a neo Geo MVS 1 slot arcade board was literally taken and had a home system shell put around it with some controller ports added and power supply ports added and BOOM you had the AES And sega new in 99 that fans wanted the arcade perfect sega Naomi experience in the home but knew not everyone could afford to put a GIANT sega Naomi arcade cab into there house lol unless your parents were super rich back then 😂, so they took that full sega Naomi board and put the dreamcast white shell around it and TADA! The sega Naomi arcade experience perfectly at the home literally no quarters needed lol, and like I said before, since sega used the same GD roms for the sega dreamcast as the actual sega Naomi GD roms it could fit an entire sega Naomi arcade rom and all the files PERFECTLY ❤️ no slowdowns, no loading times, the graphics didn’t have to be cut or scaled back on the Dreamcast, just the pure Naomi arcade game in your own living room ❤️
Nice pick up. I own a Naomi 2 myself, and play it as a stand alone console instead of putting it in a cabinet so I'll start with the basic stuff I learned along the way. I too have a sun PSU however I only use it to power my io board which is that small pcb u have in the video, from the looks of it it appears to be a Sega IO version 3 like mine although I'm not entirely sure. That little board controls the control and analog inputs for games to play. I'd recommend getting a Sega Capcom io board or the cheaper Chinese version if you want to put it in a big blue cabinet. That io board works via jamma connection so you can use a jamma harness to basically power it and get your controls running, and its preferred for fighting games. There are videos on RU-vid explaining how those io boards work, and would highly recommend it for your big blue setup. The dip switches on the filter board on the side of the motherboard control the khz for 31 or 15. You can easily look that up online and find pictures to set those and also the region for your motherboard. Worst case scenario the filter board might be bad but highly doubt it. I'd recommend buying a multi-bios, and eventually ditch the GD ROM, update your dim board the GD ROM is connected to, and get a CF card reader so you can easily switch out games via compact flash. Or look up netbooting which is kind of pricey right now which is what I use currently to play all the games available for the system using a raspberry pi. I know you said you don't like forums, and I can agree with you on that because it can be tiresome; however I'd recommend you check out arcadeprojects.com you'll find a lot of real useful information, plus there are a lot of good people on there who sell products that can help you if you don't know any of the soldering and tech stuff. I'm currently modding old PC controllers to work with certain games cuz some games are strictly analog controls but it's a journey but well worth it. Hope you get it running man it's a beautiful piece of arcade hardware, also if you'd like more PC based arcade hardware I'd recommend Sega Lindbergh, Ringedge, or some namco system PC boards! Best of luck!
Thank you so much for your comment. I’ve been away and just had time to reply. I’ll be looking back into this going forward. I think as you said, the Capcom I/O is probably what I need.
Please RU-vid point this man in the correct direction we need this. Maybe get in touch with some of the other RU-vidrs that do that kind of stuff the retro builds
One thing that I've noticed with my Naomi 2 is that while it does output 640x480 VGA, it's not the clean compatible VGA we're familiar with. Its slightly different and based on a JVS standard. Its mostly compliant most of the time but in my experience modern displays and converter boxes don't play well all of the time. For instance, with all dip switches down, it will only display on my VGA CRT computer monitors and some older 4:3 Dell LCD panels. My VGA converter boxes and my modern LCDs with VGA ports don't know what to make of it. Long story short: I would try with the VGA port on the Naomi, all dip switches down, using a known good VGA cable on a VGA CRT computer monitor and see if you at least get the boot screen. If so you can then try to get it into test mode and do a RAM check. The RAM modules on these guys are known to go sour from time to time. Let me know how it works out!
Also: I don't mess with those Sun PSUs. They worked great for many people for many years but they're getting up there in age and I don't personally feel comfortable servicing a high voltage PSU like that. I also use an ATX to JVS adapter and a nice high quality PC power supply. It works well on the Naomi but with the GD-ROM and especially the Capcom I/O requires special power considerations. I don't use a GD-ROM or traditional I/O board personally but I'd be happy to point you in the right direction if you run into any issues.
Just coming across your video I’ve spent the last year doing my own research on the Naomi 1 so I could play my favorite game of that era MVC2. I’ve been able to not only turn my Naomi into a console using modern psu and USB io on a modern OLED using an upscaler instead of the Sega or Capcom io, but also ended up putting my Naomi 1 in a candy cabinet. Hit me up if you haven’t figured it all out I can definitely help out and share what I’ve learned.
Hey Brother excellent video calling out for help. I also for the first time purchased a Naomi because I love playing MVC2. So I noticed you have the sun power supply. In theory all you would need is a power cord, if you were to strip a power cord you would see 2 wires the black and the white which match the opposite end of the naomi. They used molex connector to be fancy but you can bypass it. Typically if you don't solder you can find someone to do it for you or in a pinch which alot of people might yell about but it's only for testing purposes you can strip the wires and duct tape them together matching each color (white with white & black with black. Once you plug it into the wall on the side of the sun power supply, there supposed to be a red led that lights up if you got power. It's also good to have a multimeter to read the voltages across the pins because I hear the naomi is a very picky console and does not like to go over voltage which can fry some components from what I've read on the forums. The good thing of the sun PSU is that it has adjustable potentiometers which all you need is a screw driver. You can see it on the side of the case it has for the 3.3 volts and the 5 volts but if it were working before you got it in theory you should be okay and not have to touch it. If it is good you won't even need the atx psu which isn't adjustable. When I got my sun psu it had died because there were leaking capacitors so I had to junk it but what I did was thanks to the forums I took a dreamcast power supply and wired up the connectors and guess what my naomi powered up just fine because the architecture is almost identical only certain areas are a little more beefed up. When the naomi is on, you will see 2 LED's light up on the console by where the vent holes are on the top of the case. 1 green and 1 red which symbolize the 3.3volts and the 5 volts being okay. If you have any questions I'll do my best to help you out as I'm learning as well and asking the pros for help.
No problem bro I'm walking the same journey so I said let me help a partner out. I read also on the dip switches there 4 on the back of the console. Keep all of them off when firing up. Switch 1 is to change between 31khz and 15khz. The 15khz is for old monitors from way back in the day most usually run the 31khz which is the down setting. I also have the manual here or a pdf of it if you need it. Everything else would wire up like normal with the jamma and stuff from what I've seen. If you get it up and running you can use the test and service buttons without a game on to test the hardware. If you don't see anything make sure the USB wire that looks like a printer cable is connected to the I/O which is the same pcb that uses the jamma. Let me know how it works or if you got anymore questions I would do my best to answer them.
@@rubenmejia4881 going to try stuff this evening. Any idea on if the Jamma from the I/O is suppose to pull power from whichever cabinet it’s connected to, to offer power to the Sun PSU? Like in theory is that how this is suppose to work? First time I ever seen a power on was literally when I filmed this video, which was using an ATX PSU, only issue there is doing so offers me no way to connect the I/O at the same time.
@@AllAboutTKK No the jamma is supposed to power up the monitor from the supply of the cabinet. The SUN PSU get power straight from the wall they sell a wire if you don't solder to convert it to wall outlet. The Sun essentially is going to do the same as the ATX PSU. If you wire up the naomi to the I/O then everything from the I/O supposed to fire up in the big blue providing that you are getting power from either the ATX or the SUN
Ah so I am missing a piece. Man you might have just solved the puzzle. I don’t have the skills to wire, so I need to see where I can find the wire that gets the sun direct power from the wall outlet.
@AllAboutTKK The Naomi output a 31khz VGA signal 640x480, if that monitor does not support such a low res it will not work. I recommend trying with an older monitor or even a old CRT Monitor.
@@AllAboutTKK The video you posted about your big blue, when you mentioned u were going to put a Naomi in it, first thing I thought was "how are you going to covert the signal to the monitor" the crt in your big blue is a 15khz monitor and the Naomi outputs a 31khz signal. That adapter you have if it does not downscale the frequency safely, then your going to get stuck again. You will need to be careful as you can blow the CRT in your big blue if you force a 31khz signal to it. I am not a arcade expert but I am familiar with CRTs and how they work. I recommend you create a post on shmups forums or arcade projects outlining all the equipment you have and what you are trying to achieve, before going further as you may damage some equipment. Good Luck!
I never did. I will try that though. These things you have said have been a tremendous help. When I tel you I’m smart as hell with a lot of things, I honestly feel insecure being so dumb about this arcade stuff lol.
So.... The question is.... Have you got it working??? I've bought a load of old Naomi boards (House of the Dead 2 board included with one). Mine has exactly the same issue as yours. No video. Please let me know if you got it working and what you had to do to fix it.
@@AllAboutTKK savage...... I've heard that the RAM chips around the fan are a common fault for not displaying video. I'm in the same boat as you now, trying to fix a board I'm learning on as I go along.
The power supply fan should come on and u could use a voltmeter to see if it's putting out power as for using the other PC ATX power supply it probably is fine but would you should/need to just put the connectors from old supply on the correct wires off the new pc power supply. (UNless u can buy some adapter) GD rom unloads the game from disk to the ram device plugged into the top of the Naomi it's just to increase load times and keep wear down on the GD drive. U can take video and sound off the Naomi VGA output on the side next to the RCA outputs for sound. Its a 31KHZ Signal Not 15Khz on that VGA out so make sure the monitor or tv can read that not just 15khz.. or u can use that board that's loose its called a Sega Naomi I/O Board Arcade VGA JAMMA Converter Board and should allow u to use ur current jamma Set up , The 5Volts is negative on that i believe I'm not sure of memory , but it should be straight plug and play with most Jamma Cabinets from that same timeframe.
Damn I’m sorry I missed this comment, I’ll be sure to use this as I haven’t touched this thing in a minute but now I have Capcom I/O so if this does not help we shall see.
Please check if your naomi starts with a game instead of the dimm board with the gd-rom drive. if it starts, then you get less or not constant 3.3 volts & so it doesn‘t start or you get error 01.

i have a japanese mvc2 naomi system that boots but crashes right after the ram test, i gave up on it and put it on my storage, let me know if you got yours fixed
My friend the man you want to talk with is Anthony of the Video Game Esoterica RU-vid channel. I guarantee you he can help you out. I'm gonna link this video to his discord.
@@AllAboutTKK hopefully that link to his discord works. Anthony is a super nice guy and has one of the most unique gaming channels on RU-vid. I'm sure he can assist you in getting that baby up n running. I'm a diehard Dreamcast fan and hope you get that Naomi up n running. I know tons bout mods etc on home consoles but I unfortunately don't know shit about arcade hardware
the naomi won't start because you haven't connected the 1 0 pcv to it, I see that you have it, it's a security measure on the internet there are tutorials
I wish I could offer help, happy to do some googling myself and if I come across anything helpful I'll let you know. I've just been researching a Naomi setup myself and came across your video. I at least hit like and subbed!
@@AllAboutTKK Not sure if you made any progress. I have a Naomi coming so pretty excited about that, its going to be a while with parts coming from all over the world so I've been doing as much reading up as I can in the mean time. Anyhow, that board you talked about at the end looks like the Sega IO board (there are several different brands that work with Naomi, I bought a modern one made by Tuscon Logic). If I understand correctly, that board attaches to the Naomi just via a standard USB cable. If the Naomi doesn't see it attached it may not even boot up if I understand correctly but I think you can pull VGA off either the Naomi or the board once you have it hooked up. Hope this helps.
