Sega Naomi Error 22

[Retro Arcade 562]

So I've been attempting to get this GD Rom setup booting up for some time now. Was gifted the parts needed including some great games from a few different friends locally. My goal at some point will be to setup a Netboot setup, already ordered a Net Dimm board V4.02 from Sheep_nova on here. But until I can afford to finish buying whatever other components I'll need to do so I'd love to be able to enjoy this. These are the visible dip settings I currently have on my setup. Am I missing anything, or is there something i should check out for? I am completely stuck at this point.

The ERROR 22 is 99% a connection issue between the DIMM and the main board.

please check the white connectors on the naomi if there are small pieces stuck in the connector. Check if the dimm can make full contact with the naomi (you can remove the top cover from the naomi and seat the netdimm - sometimes the covers do warp)

Reseat it.

If the error persists: Go into the Setup menu and try to run the DIMM board test (and check what firmware the DIMM is running)

In some cases it -can- be a DIMM ram fault error.

Please remove the supercap, it leaks somewhen and can cause damage to the pcb.

Gonna definitely try out what you mentioned above. Hopefully it's something simple, thank you for all of the info and help.

Also be sure to check your voltages. If you have a battery in your dimm, try removing it. A low/dead battery will cause a voltage drop during boot.

Does this motherboard work with other games or dimms? Does this dimm work in another motherboard?

I don't have the battery hooked up in the dimm currency, the mobo works perfectly fine with all other game carts. Also I've tried going into test mode while the dimm is installed and when i try to do the dimm test it times out.
