What do I do with the chips from my B board & other pesky questions ...

I have a new question regarding the JAMMA connection on the CPS2 A board

Do the stereo audio jacks on the A board appear on the audio pins on the standard JAMMA connection as well ?

If not what if anything is on those pins on the CPS2 side ?


And speaking of JAMMA pins , there are more then enough empty pins to add extra buttons, why do we even need a kick harnesses ? I don't get it. I have my MVS wired so that I not only get two player button 4 but the two "select" buttons yet there are still two rows of unused pins that could account for two extra P1+P2 action buttons ? What gives ?

Is there a way to wire the kick harness pins to the JAMMA connection before it leaves the A board ? Some sort of internal hack ? I know that most long time cabinet owners already have their kick harness wired up but for MAME guys, we use an interface like he KEYWIZ or the i-Pac ... I have six action buttons that are laid out exactly like a CPS2 fighter cabinet, two rows of three action buttons along with P1 +P2 start buttons. additionally I have three extra buttons I can assign anything to, typically COIN 1 + 2 plus reset or escape

So for me, I would like a way to keep all the wires for any buttons come out of the JAMMA harness because those are already connected to the buttons I need to use even though some are empty at the moment

Actually the region regards to the program ROMs only. For example, there's nothing keeping one from putting a Japan game on Asia or Mexico board set.
 
Follow up to my question about cps2 kick harness, I came across a JAMMA PCB that has a a CPS2 kick harness molex with just the P1+P2 kick buttons wired to it with about 6 inches of wire with is then solderer to a small PCB that acts as a pass through

Which then gave me the idea that I cold create my own with this

I can make my own little pass through with the kick harness I just ordered. I will just need to shorten the length of wire attached to it

But they still leaves me with question of why don't they use the spare pins on the JAMMA harness for the extra buttons in the first place ??

There is plenty of room for them.

Just go with it. Which you are doing. Life is too short to ponder those things and it is pretty academic at this point; you're talking about 20 year old decisions made by Capcom. No point questioning those now.
 
Haha.. Well I'm not losing sleep over it if that's what you mean

I'm just a curious person. Also it's not just Capcom it's pretty much everyone and then with the advent of the JVS interface options, there are boards that have both AND a kick harness with different connectors.

Namco used a shorter edge connector

I got one of theese to deal with that

So for my own issues I got it covered but I am just really curious if anyone has any insight into why such a robust and expandable format like JAMMA was not utilized to the fullest.

Maybe it's for the same reason that console manufacturers keep reinventing the controller, so that with each release they can charge $50+ for a new controller. It could be that simple. Make arcade owners pay more for cables and shit
 
More likely, Capcom wanted to stay out of the furniture business. What do I mean by this? Most of Capcom's games from the CPS2 and beyond were sold as kits. SF2WW took the world by storm. Many JAMMA cabs were modded just accommodate that game's 6-button configuration. It wasn't until the middle of SF2WW reign that we saw cabs made specifically for SF2WW 6-button layout. Most were just re-drilled Midway cabs up until that point. It wasn't until SF2CE that Capom made a dedicated cabinet, commissioning 3Koam first then, Dynamo to create the Big Blues. Sadly, the CPS1 kick harness wasn't as robust as the CPS2 kick harness. CPS2 had way more pins allowing for future expandability. So with the CPS2 came a standard that allowed Capcom a platform for current games, future games, and still be sold as kits fitting in standard JAMMA cabs. They carried this same platform into two other platforms since the CPS2: Sega Naomi and CPS3. So they didn't make operators 1up like console manufacturers do with controllers.

I was told a recent story where by when us Capcom's arcade division shuttered its doors, they just pushed the remaining Big Blues off the docks to smash them. That means the SF2CE and Q-sound Big Blues made around 1991 were taking up floor space for a good 10 years. They never again commissioned a furniture maker/wood making company/or whatever 3Koam or Dynamo started life as to build cabs for them again. They got out of the furniture business; stuck to kits that fit JAMMA standard wired cabs. But who cares at this point. Just go with it.
 
Very interesting !! See that's why I ask these questions :D


(And I do care actually. History is important)

Oh yeah , so what about the stereo RCA QSound jacks ... Is there any sound coming off the JAMMA pins? Is it mirrored or just mono or what?
 
In the CPS2's system/test config, if set to mono, then JAMMA audii. If stero is set, then stereo output through the RCA's.
 
Street Fighter 1 had a dedicated cab and it's very well known since it used pressure pads and a vacuum system instead of standard arcade buttons.

There are only a couple in original form known to exist and only in Japan, the rest were all converted to 6 button form or destroyed, finding one with the original vacuum system has become a holy grail search for American collectors.

The JAMMA edge can support up to 5 buttons for input (which the Atomiswave uses) but as acblunden pointed out when SF2WW exploded onto the scene most cabinets only had 2 or 3 button setups, so it made life much easier to have the kick harness to add the extra 3 buttons rather than trying to have operators solder extra connectors to the JAMMA edge

That story about Capcom destroying the big blues is sad, the end of an era :(

thank you for clearing that up. The stereo jacks are perfect for my system because all my audio is separate from the JAMMA connector. I currently have three separate stereo jumpers feed the stereo amp. A fourth pair won't be hard.

Wow, I did not know about that, thanks for the details . I am aware of how 2D fighter enthusiasts are picky about joysticks and button configurations. It's understandable, especially in competition.

I'm surprised that no one has come out with a new vacuum system. The same way other reproduction hardware has been made by hobbyists.


Speaking of which, I am in need of a new P1 joystick, the one I have on mine has been worn down and sticks occasionally, always at the wrong time. I prefer a 4/8-way stick but am not married to it if the argument for a dedicated 8 way is a good one

I don't want to spend more than like $35 if possible.

Any reccomendations ?
 
The iL Eurojoystick. The original Happ Competition sticks from that era, before Happ commissioned a Chinese company to make their current Competition sticks. Don't buy the Happ Competitions. Those are made in China and suck. Consequently of interest, the iL's are of better quality and made in Mexico. Go figure.
 
Yeah I have a HAPP now and it is not that old considering. It fails regularly where it will get stuck in one direction even when it Is not being pushed, very annoying. Also it started to squeak recently lol

I'll def look into that eurostick, thanks a lot!!

I'm personally a fan of Japanese sticks, I use either Sanwa JLFs or Seimitsu LS-32, the Sanwa are better for fighting games only but the Seimitsu are a better universal stick (they're a bit stiffer so better for shmups etc)

I like Sanwa buttons though, OBSF-30 and OBSF-24 all the way

The reason no-one has reproduced the vacuum system is in order to do that you have to have an original one to reproduce it from, no one has been able to get access to a working system to see how it works, there are people trying but this system is almost non existent :(
 
I've heard about sanwa & seimitsu. I'll check em

And wow, it truly is the holy grail.
Hard to believe that documents about them have not been released over all these years.
 
what is the expected pricetag of the Seimitsu? I see them from China for about $27 and then a couple from someone in Kansas for $160 ???
 
If you want to get them from Japan directly, riverservice or Akishop are your best bets (I prefer Akishop personally) - there are a lot of fakes out there so I bought mine direct (also I couldn't find an Australian store that had the colours I wanted in stock)

If you want to go with someone in the US since there are a few good resellers, I think Paradise sells them, FocusAttack is another good American site too

Sticks run about $35AUD I think? So $27USD would be about right.
 
That's a big help, thanks! Thinking about replacing all the buttons too. At least on the player one side

What is the difference between the two pins VS 3 pins thing ? The HAPP stuff has three and the sticks & buttons you pointed out have two.

To tell the truth, I have no clue what the unused third pin even does on the HAPPs
 
Saw this on eBay

An hour after it was brought up here, there it is.

Is he crazy asking that price for it?
 
Sadly, he is just flipping it. It was sold on eBay 3 months ago for half the price. Same cab. Yes, he is crazy. No one will pay that much for it.
