Just curious if anyone has encounters error 4 from Media Bd type 3 Triforce. This just happened on my test unit I have been using for like 18 years. Its set up to run GDROM, CF, SSD and I have updated firmware obviously. It just came up with this error 4, Bad serial number on media bd. Sure enough, in system info, that sn is blank. Never really paid attn to it. Also never new it had sn protection. I have the special ROM to set serial ID on Naomi but nothing for Triforce. Anyone have a clue on this?
