Sigma Raijin questions

[Sinneslöschen]

Hi,
I hope you can help me. I am thinking about buying a Sigma Raijin, but I have some question:

-how can I connect PCBs that require 6 Buttons that are using a "kick harness"? According to the pictures I found it has a JAMMA connector (or is it a special connector?) on the side and audio/video outputs in the rear. How can I connect the additional buttons. As far as I know there are no shmups using a kick harness - I hope will help me anyway

-Can the buttons be replaced with 30mm Sanwas/Seimitsus?
They look a bit different compared to the usual Japanese ones.

-Does anyone have the RGB-out pinout?

-Does it come with a JAMMA extension or do I have to buy one separately ?

Thanks in advance,
Sinneslöschen

Howdy

-how can I connect PCBs that require 6 Buttons that are using a "kick harness"?

That's exactly how you do it -- with a kick harness. The only one I have is for Sega System 24. I use a combination of the kick harness & jamma harness to play these games.

-Can the buttons be replaced with 30mm Sanwas/Seimitsus?
They look a bit different compared to the usual Japanese ones.

I've only tested these for a few moments, but from what I know (and felt) they are the same buttons found in the 9000TB controller, which are 30mm Seimitsu. If you want to swap them, you can, but I'm not sure how much work is involved. It is more than just popping in and out as each button has autofire.

-Does anyone have the RGB-out pinout?

Comes w/ the unit, although in Japanese. I'm sure if you search around (or ask) it can be translated.

-Does it come with a JAMMA extension or do I have to buy one separately ?

Doesn't come with one, but a recent trend is for the shop to throw one in as a special package. Just depends on where you buy it.

Thanks for answering all my questions so quickly in one single post.

However, I do not get the "kick harness" thing:
I have never seen one but I suppose it looks like this

The connector goes to the CPS/Naomi/whatever, but how do I connect the female disconnects to the Raijin.

Do I have to wire them directly to the buttons like using a cab??? I know that the "normal" JAMMA connector can be used for 4 (NEO GEO) or 5 (Atmoiswave) buttons. Is there a special JAMMA connector for the addition buttons?

Thanks again.

The one I have looks nothing like that. I'll have to dig it out, but it's basically a Special connect connects to the PCB, then your JAMMA connector from your Jamma harness connects to that, then the other end goes into the Raijin.

What games are you wanting to play on the Raijin?

It woulde be great if you can post a photo of this "mystic" harness.

I have an old 3 button cab with a horizontal screen. I want the Sigma to play anything else, e.g. bemups that require 4-6 buttons (Street Fighter II/NEO GEO) and -of course- tate shmups

I think you'd have to cut the large metal tips off the kick harness and connect the inner coil the the fingerboard that the Raijin uses. To have additional support (buttons 4&5 on Neo-Geo and Atomiswave), you'd need to solder 4 wires directly from pins 25&26 on the Jamma harness to the fingerboard. To do all this, you'd need a Raijin fingerboard pinout.

Or as GP suggested, there are integrated Jamma harnesses that already have a kick harness or the extra buttons.

The only Tate (vertical) oriented shmup PCB that uses 6-button scheme is American Sammy's Daioh PCB. Buttons 1, 2 and 3 are accessed through the Jamma interface while buttons 4, 5 and 6 are accessed through a "kick harness" adapter (and would have the fourth, fifth & sixth buttons on the arcade cabinet control panel wired directly to the Daioh PCB itself via kick harness input connection -- which would be only three wires per player for a grand total of six wires altogether for both players 1 & 2).

If this is sounds too confusing, you can just play the USA version of Daioh PCB in original Japanese 2-button mode via a 2-pin header on a certain jumper that's located on the Daioh PCB itself.

Good luck on your search for an American Sammy produced Daioh PCB... ^_~

Here is a System24 board w/ Sega harness connected to a Sigma AV7000.

Just imagine two harnesses making love.

You chop off the disconnects and solder the wires to the fingerboard on the main harness:

this is the pinout of the Sigma fingerboard/22-pin connector:

Button 4 will work as jamma 4 (MVS D button) and CPS2 light kick and button 5 as jamma 5 (MVS select, Atomiswave 5th button) and CPS2 medium kick while Button 6 will be exclusively CPS2 strong kick.

Thanks everybody for your help. Finally all kick harness mysteries have been revealed

Now I have to wait and see if can get a Sigma.

So just going on how JAMMA is supposed to work, I could solder a kick harness to the fingerboard and it'd work fine for any game that requires a kick harness? Most games aren't going to pull some stupid "you must use OUR harness!" bullshit, right?

Not that it matters a whole lot, since probably the only PCBs I would buy are Cave/Raizing shmups anyway, so at most I'll need three buttons.

It is not that easy. There are different connectors (to the PCB) for CPS1/CPS2-3/Mortal Kombat kick harnesses:

You'd need to make adapters, like the CPS1-to-CPS2 here:
