Just linked up my two universals, and I've found that out of the three fighters I have, only Guilty Gear XX ^Core supports linked JVS I/Os.
I was disappointed to find that CvS2 and Project Justice don't support a linked JVS I/O setup. I'm going to wire in a JAMMA harness into each cab anyway, so I'll be running them linked via the Sega JVS>JAMMA I/O, but I was wondering what other games do and don't support linked I/Os.
So far I've gone through the following games. These are all been run on a Naomi with the Japanese version G bios.
GGXX^C - Works
CvS2 - Doesn't work
Project Justice - Doesn't work
Puyo Puyo Fever - Doesn't work
The only other Naomi games I have are Border Down, Ikaruga and Virtua Tennis, which I've yet to test.
Does anyone else know any games do and don't work? I've got Melty Blood Act Cadenza Ver.B on the way, so I'm hoping that will work too, as I'm hoping to get some Vs gaming done before I add JAMMA support.
