New net city or net city control panel lockout for CVS2

[VodkaGobalsky]

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.

Replace the IO with another later revision. I have this working in h2h NNC for years. I will take a photo of my IOs.

Ah is it just a Sega I/O?

I got another spare with this one. I wonder if it will work.

That is the official Sega I/O that comes in Naomi Universal, Net City and New Net City.

When I used to have a New Net City, I actually replaced this I/O for the Sega USB I/O (type 4) and it worked great for most games. It did not like the Y2 system though (KOF 2002 Ultimate Match).

Since you live in San Jose, you can borrow a Sega USB I/O and see if it gives you any issues. They are the same exact size and the pinouts are the same too. Plus, they have USB, so you can use it on a PC (D input only). Drop me a DM if you re interested.
