CVS2 Naomi linked freezes

[keiichi331]

Greetings!

I am at a loss here! Here is the set up

- 2x H2H Sega New Net Cities set up

- First set up : Naomi 1 mono, NetDimm, raspberry pi loader
- Using the VS link board to set up H2H
- powered by the machine SUN PSU
- Audio, Video , Controls all work
- Issue: After around 30 minutes, all controls lock up and nothing works.


- Second set up : Naomi 2 mono, NetDimm, raspberry pi loader
- By passing VS link board, direct splitting audio and video straight from N2 mobo
- Directly linking the SEGA JVS I/O boards with a super long cable from p2 into p1 SEGA JVA IO
- powered by the machine SUN PSU
- Audio, Video , Controls all work
- Issue: After around 30 minutes, all controls lock up and nothing works.

I have no idea why this locks up. It only happens on CVS2. I've looked around and it doesn't seem like anyone has any solution. Someone people see it some people don't. This is highly annoying and does anyone have any idea what's going on here?

Hoping someone who's seen this has a solution here.

Same issue as Vodka?

Thread 'New net city or net city control panel lockout for CVS2'

Jun 8, 2025

This is known issue to all new net city or net city owners that when playing cvs2, the controls will be come unresponsive randomly. The entire panel is unresponsive including the reset buttons. Only way to fix it is to power cycle or reload the game if you have a wipi netbooter. Our theory is there’s a bug in the code affecting the I/O on these machines. It only freezes between rounds or games. Never during a game. Anyone have any experience dealing with this or have any idea how to fix it? It seems to be only an issue with cvs2.

It's probably the I/O, from the sound of it.
