Hi everyone!
I have a question regarding my naomi since I'm going crazy here XD
I have a netdimm and a regular dimm. Both gives me error 22, so I de-cased both and seated them correctly and still have the same error in both. I even swapped the lower board just in case since apparently it is the same.
I then noticed my naomi board have some wires glued and I'm not sure what they are for, but I believe that might be the cause?
Here are the photos:

Maybe some of you know what it is about or what they do This Naomi was bought on a trip to Japan, on a arcade board shop so I don't know why it has that but it works with regular games, like Virtua Tennis.
I use a PSU power supply, so I'm guessing it is not a voltage problem?

Thanks in advance and happy Christmas everyone! :)
 
What is a PSU power supply? Power requirements are different for netdimm vs a normal game, so I’d start there. Measure the 5v and 3.3v under load right at the Naomi. Possibly you need to adjust the 3.3v line.

Maybe there's something wrong with my set up. I uploaded a picture just in case:

btw yes, the daughter netdimm board is not in place in this photo XD sorry

Those wires (trans/resistors are normal an the Naomi 2. Have you tried to use those dimms in the Naomi 1 type motherboard fo rule out that the mobo is working correct,? Also check for any bend pins on 1 of the 3 slots
 
Ekorz, thanks a lot for the link :)

AMS, but this is a Naomi 1 motherboard. Are they also normal here? I don't own a Naomi 2 . Also all the pins are perfectly fine
 
Sorry the dark round edge made me think you had a n2 :) yes they are also there on the n1
But did they ever work or did you buy them with error 22
As I think they are dead (burned buffer)
 
I bought them from different sellers. The regular dimm a couple of years ago. Could be a coincidence, but it is strange that both don't work right?
 
Hi! I bought the multimeter, but I didn't need to use it thankfully. I have bought another netdimm and it arrived yesterday.
I tried it and it works flawlessly!!!! :))) So my other dimms are faulty, but who cares? It is working!! :DDDDDDD
Thanks everyone and specially Mitsurugi for all the help!!!!!!

PD: One question, can I load the new atomiswave unreleased games with Pi force tools? not sure if we need someone to convert them to naomi first :O
And how does pi tools work with triforce? does the pi force tools recognize the triforce and shows up a different game menu?
 
Well, you should be using the multimeter and adjusting your voltages - or you’ll soon have 2 dead netdimms.
