Hello,

I have a Sega Naomi Dimm cartridge that has firmware version 1.02 on it. This is a Dimm cartridge and not a net Dimm. I have a GD ROM system but can't find any upgrade disks online.

Does anyone provide a service of upgrading it to the latest version 4.02?

I appreciate any help or information on this!

Sorry I did not see this earlier. Its slim chance you can do 4.02 without NetDIMM media bd. I have tried many times with maybe 1 in 20 working on SCSI. No clue why and I am Sega Guru. I have like 8 different versions of 4.02 also for whatever reason and none work solid with SCSI only.
