I made a discovery yesterday. I tried booting a game with the jamma harness unplugged from the capcom i/o (i had it plugged into a pandora box instead) and games started to load without problems. so I believe CamoYoshi's idea its related to power not getting to the dimm is the problem. the...

Cleaned, reassembled screwed in and same result even mashed those connectors in as hard as i could. worked great for 4 hours last night i even tried tilting the board while testing and it seemed fine. loaded around 5 games before putting it back in the cabinet. next day it was back to its old...

Update. I think I might have figured out the problem but I'm not sure. I think the reason the netdimm kept failing in the machine was because the board wasn't level. I kept the board on the the shelf where my control panel is. but the shelf is sort of at a slight slant. I put the board on the...

I haven't seen this before. it might be related to the monitor type. I've played the game in 15khz mode without this issue. some of the files in the netbooter are wonky. For example, radirgy noa has no music during gameplay if you set your cabinet to freeplay mode. but if you insert credits the...

I got the isopropyl and tried brushing the contacts to the best of my ability. Same stuff kept happening. I pulled it out of the cab, netbooter connected and loaded a game. Put the motherboard back into the cab failed to connect several times and loaded twice before failing again. I am starting...

The harness is plugged into a capcom i/o. also when i say the naomi works better i just mean connecting to the netbooter. i dont bring the i/o board out when i try to fix the netdimm. Im going to try and find some brushes and isopropyl alcohol today to see if that does anything. is there any...

the issue is i'm kinda new to working on arcade hardware. all the wiring inside cab besides the naomi itself (jamma harness, marquee light, speakers, coin/ service buttons, montor and isolation transformer) is going through the happ power supply. i wouldn't even know where to begin with cutting...

my power supply setup is a little bizarre. I use this pc power supply with an adapter that coverts to the proper voltage. I've used a multimeter on it and it comes back with the right levels. however inside the cab itself is a happ power supply. i plug the naomi power supply into the outlet on...

I dont get an error message per se from the naomi itself. My setup is the wipi netbooter setup with a raspberry pi4 with a 3ft cat 5e cable. the way I tell If I'm having network issues is if the netbooter tells me my system is offline. my machine may start in online mode when I boot up but when...

I've used air dusters on the connection pins before. I have not used isopropyl. I'm not sure how to get inside the thin contact points. are there special brushes for smaller areas? or will a cotton swab be enough?

I've been having this problem with my netdimm for over a year now. After a while my netdimm stops connecting to my netbooter setup. sometimes I reseat the board and it fixes it for a few days, other times its the ethernet cable needing to be swapped for another one. I'm at the point now where I...

I figured out the problem. It was the bios settings. apparently when capcom distributed the game internationally they disabled the c-panel settings. So if you want to use pads you have to run the japanese version of the game. controllers are working now.

i wish had a new net city cab i could understand where those wires go. other games work. I've tested mvc2 and that allows me to use the pads. the keyboard titles also work with it. I just cant figure out what this jumper "A" thing is. I was thinking it would be inside the motherboard itself...

I'm using a capcom i/o when I go to the game config settings I am unable to see any option to select anything for c panel use there is no (on or off) selection im assuming its because i dont have jumper positioned properly. there's no i/o error I got the maple2naomi for friends that would prefer...

I got myself a maple2naomi adapter I am trying to get cvs2 working on it. According to mister addons website, I need to set a jumper to the "A" position. I was wondering if anyone knew which jumper they are referring to, and if changing it affects other games.

I guess I'll give it a go. what's the best kind of mounting bracket for a 27 inch? the one i have inside my cab right now is a wood square I can pull out and rotate. I was originally thinking I was going to just have 2 slabs of wood on the top and bottom. Should I go for this 4 corner square...

I have been on the fence about this for a while now. I have an arcade cabinet with a cga monitor and I've been really wanting to get a vga monitor put inside instead for a naomi setup. In all the states near me I've only managed to find vga/ trisync monitors that were 27 inches. I visited a guy...

Hi, I have a net dimm setup on my cab, one day a couple months back my ram went bad inside my net dimm. it was a brand new stick I got off ebay and was one of the listed compatible versions I saw listed on this forum post...

I feel like I am looking for a unicorn. I dont know if 25" vga crt monitors even exists. I've been searching for over a year now on facebook and on ebay and most high res/ 31khz monitors are 27" and up. My cab can only support a 25 inch monitor or smaller. I am hoping to find one that can fit in...

Somehow I miraculously got the wipi to boot with a cat 5 cable. I was just in the middle of getting python setup to try your method and it just connected without any problems. Thanks for all your help. Looks like the firmware was fine after all.
