CVS2 Naomi linked freezes

I have my New Net City (sega jvs io) linked to my Blast City (sega jamma to jvs io) and I haven't encountered this that I can recall. How long does it typically take to crash?
 
Which JVS IO do you have @notsonic ? Exact type number please.

Also for the others having issues, please state your mediatype i.e. gd-rom, CF or netboot.

If you are using CF or netboot, please provide the md5 checksum of your image.
 
Some potentially helpful data from me...

It's been a very long time, but some friends and I used to run 1-2 pairs of CVS2 on various combinations of cabs off GD-ROM for up to 8 hours, never had issues.
  • Capcom I/O to JAMMA, GD-ROM
  • Namco JVS I/O, GD-ROM
  • Konami JVS I/O, GD-ROM
I'm far from an expert here, but I was also starting to wonder if it could be some weird bug in the game itself that may be causing issues with certain JVS I/Os. The issue with the td-io is interesting, and I wonder if it is worth reporting as an issue to the project GitHub?
 
Okay time to try

Post in thread 'Sega Net City vs link board (838-13816-91) info'

I had Capcom Vs. SNK 2: Millionaire Fighting 2001 running in link today. However, it locks up frequently between rounds (and always between, never during). When it locks up none of the controls work, not even the test button.

I haven't had issues with other games. It's the earlier version of the game (Rev A, GDL-0007A), maybe a bug in it?

I think it is reading correctly. Next time it freezes, I'll connect it again to see if I get any signals.

Nice now we are getting somewhere, just leave it connected and watch the data fly by. It has no impact since it's just a tap.

@Big_P Big_p which 3V3 regulator are you referring to ? Got a picture ?

The TD-IO has a built-in sic437a to provide 3.3v at 7A from the JAMMA edge. It's a bit like the Capcom I/O except it can run a netboot setup (if heatsinked)

Apologies for the bad picture with flux everywhere I am not at home and was taking that for another reason altogether, the SIC437A is the big black thing with flux all over it.
