Cyber Lead, River Service JAMMA2JVS, and Street Fighter 2 (and Gals Panic 2/JAMMA in general)

[AMurderOfCrows]

Hey everyone

I have a pair of Cyber Lead cabs, a river service JAMMA2JVS, and a street fighter 2 board i'm trying to get working together.


When hooked up, i get video and audio, but no controls. I know the controls work as i am able to use Tekken 3 and a Namco unit without issues.

i *THINK* it is JAMMA specific, as i also have a Gals Panic 2 board that i hooked up. It has the same problem: no controls.

i'm at a total loss. Searching for Cyber Lead and JAMMA resulted in nothing that looked like it would help.

Have you confirmed the SF PCB is working as normal on another (maybe native JAMMA or with a different JVS>JAMMA adapter) cab?

[Rossyra]

Locked controls can be caused by a grounding issue. Does the service button work?

[AMurderOfCrows]

Thanks for the replies so far!


So, i have no way to confirm myself that SF2 works, but i CAN tell you that another JAMMA board (gals panic 2) does the exact same thing.

I'm not sure that the controls are locked so much as simply not connected right. The card seems to work for powering audio/video, but i wonder if maybe the USB port on it is shot or something.

I don't have any other I/O boards, so i figure my next step is to get a new JAMMA to JVS board and try again?

I also am not sure about the service button. Where would this be located, and what is it supposed to do? Does the fact that the controls work on other, non-jamma games mean anything?

That points at a problem with the JVS>JAMMA adapter because your cabinet I/O board seems to work fine if Tekken 3 is working fine.

JVS>JAMMA boards are quite thin on the ground but they can be found. If you can get your adapter looked at by someone (or yourself) that'd probably be best...or maybe make up a JAMMA loom for the Cyberlad yourself, that way you wouldn't have any input lag (which the riverservice adapter supposedly has).

Figures. I tracked down a couple of Namco JAMMA to JVS cards, going north of $350 each, which is almost as much as i paid for the cabs.

I don't have the knowledge / skill / time needed to make my own loom, so i can only hope that maybe there is someone i can pay to produce a pair for me, or i'm stuck buying the I/O cards i guess.

thank you again for the help

The test and service buttons are on the JVS/Jamma adapter.

[AMurderOfCrows]

The test and service buttons are on the JVS/Jamma adapter.

ah ha! Yes, they do. Service sounds like it gives credits, test sends the board to the config screen (like bank C dip 8 was flipped On). No input from the USB though.

really thinking the USB on this I/O board is the problem now.

[Rossyra]

Try a different USB cable. If you have the kick harness connected, unplug it.

okay, will try that, but does it make a difference that the controls work as is for other games and that it happens for both cabs?

[Rossyra]

Best try the easy stuff first before you start dropping piles of cash on adapters IMO.

This.

Might be worth checking the pins on the USB port and the soldering of the USB port on the board for any dry joints. I've had pins on USB ports break off or bend up before.

I did a little JVS lab work a few weeks back, and had the riverservice adapter on the bench. From what I can gather, it does not support multiple IO boards. I'm not 100% sure how JVS works on the cyberleads, but it's more complex than most cabs.

What you can try is to make sure the IO board has a USB cable directly to the riverservice adapter, and NO other usb cables connected.

Worth checking this as I remember the USB cable in my Cyberlead going to the ntsc board at the back of the cab and then from there to the IO board.

Well, i did a different test. I hooked up a micro usb cable to the cable slot of my Tekken 3 board and hooked that up to a portable mouse. When the cab turned on, i got lights on my mouse.

i tried the same thing with the riverservice card and didn't get anything.

Invzim's suggestion is a good one, I completely removed the video board on my Cyber Lead

That is not smart, jvs IS NOT usb - the signals are completely different.

Perhaps not, but it proved a point fairly quickly with what i had available. the river service card's port did not cause the mouse battery lights to light up, the Tekken 3 board did. Unless the two boards do not provide power at the same pins, which would strike me as incredibly odd, I should have gotten the exact same reaction.

Yes, this would have been infinitely smarter to test with a multimeter. No, i didn't have one at the time.

[Rossyra]

So did you try plugging the i/o direct to the jamma adapter?

Not at all I'm afraid - JVS does not supply power on any pins like USB. You have a sense line which is pulled high by a pull-up resistor (often internal to the controller chip) until the slaves are initialized - then it is dropped to 0, this merely a signal and not intended to drive anything the way USB does.
