Delta 32 JVS I/O Board Error

[Arikado89]

Hi everyone,

I've got pair of Delta 32 cabs that run Tekken 6 bloodline rebellion game in back to back setting as shown in the picture. I replaced the game with KOF 02UM board and didn't change anything else in the cabs. However, during the gameplay I get black screen with test mode error message. Oddly, the error screen appears while I connect the USB B cable from JVS I/O board of the main cab to the P2 cab JVS's board. Besides that it happens in different timing, usually from 5 to 10 mins and sometimes after 20 mins. As long as I am not connecting to the P2 cab JVS's I/O board the error message won't occur.

Any idea about identifying the cause of this error?

Thanks in advance.

Likely the River Service IO being not totally compatible with the game when daisy chained.

For the record, I have had issues with this IO with some Type X games. Similar problem that it wouldn't instantly throw a JVS error, but work for a while, then error.

It's a real bummer that River Service IO has compatibility issue with some games. Luckily, the cab supports both Jamma and JVS connection. I'ma hook the game via Jamma connector, but I have no clue how to do so for the P2 controller.
Any suggestion would be greatly appreciated!
