CPS1 Multi. Official Thread

dos said:
Mine should be here on Friday, fully expecting to get an FPGA due to how late I ordered but not the end of the world because it's just sound stuff and I've never been one to stress about audio (everything mono, don't mind stuff like stock Aero speakers that lots of people say is unbearably bad) so I definitely won't notice a difference

Yup. You'd also would have needed a Qsound amp equipped cab for it to have made any audible difference. Think that amp would have been found only in these 4 cabs:
  • Capcom Impress
  • Capcom Q25
  • Capcom Gen 2 Big Blue
  • Capcom Gen 3 Big Blue
I was just remarking on how random it was, with my buddy ordering his multi sometime in 2022 (I think April). Personally, I was hoping for the FPGA. My reasoning, CPS1 customs are known to fail. CPS2 A-boards with the Qsound chip are known to die with no desuiciding available. The Qsound chips probably came off the same fabs. A born-on-arrival modern FPGA implementation has a better chance at this point in time to outlast a 27-year old IC. I am going out on a limb and will postulate that not even half of the ppl that bought this multi have stereo-based cabs, let alone Qsound amp-based cabs. All that coupled with Darksoft, probably even in collaboration with Jotego, Eduardo Cruz, Apocalypse, and others, confirming there is no analyze-able logistical difference means it is much ado about nothing.

The only thing that irks me in all of this is my packing box arrived with clear packing tape. Not a stitch of Darksoft/Walsdawg Arcade tape. Damnit. I was #8 on the interest list. Damnit all to hell.
 
Sorry if it's been asked already but I didn't see a specific answer.

Where do I plug in the kick harness for SF2WW? If I'm understanding correctly the location of where the kick goes depends on the game?

Also, is there a separate location to set dip switches or do you need to reach under the multi and adjust them on the bottom board for each game?

Multi is working great so far by the way, thank you!

Exactly! it depends on the game, but the multi works 100% like the original, so google the sf2 manual and see where it plugs.

No separate location and it's not possible to change them in an easy manner once everything is assembled. That's the reason why @Mitsurugi-w is making the remote Dip Switch PCB that will solve that problem. He should start selling them in less than a week.
 
My multi finally arrived from HighScoreSave! Cant wait to get this thing up and running, particularly with all the additions Derick and Mitsu are doing.

Huge props and thanks to @Darksoft and everyone involved in putting this together.

There has been a lot of back and forth on the topic of Qsound and the "Qsound" amps/speakers on these cabs.

Let's demystify this qsound thing, as far as I can tell from everything I have read, schematics of the qsound amp, etc... The amp and speakers are nothing special, it's just a regular amp and speakers. Nothing more, the fact that the speakers were made by Yamaha, again is nothing special, its a speaker.

Qsound was a mix of different "technologies" to produce a 3D virtualization of different mono sounds. It basically an algorithm they came up with after a lot of listening tests to find the one that works the best.

In the case of the CPS1.5 games/hardware, they are using the Q1 tech/chip -

Capcom basically licensed their software and used their Q1 tec/chip to act as a DSP on the CPS1.5, etc...
I'm thinking this was more of a security/anti-bootlegging effort and well also a new attractive "feature" for their games to set them apart from their competitors that were only using mono and/or basic stereo at the time.

I have seen also talks about the Yamaha speakers used in some of these cabs being special in some way. Yamaha also licensed their Qsound software, again there is no Qsound tech/hardware being applied to/built into the Yamaha speakers found in these Qsound labeled cabs by Yamaha.

Attached is a pdf of the describing qsound tech for OEMs

The way I see it Capcom is basically using the "3D" audio authoring/mixing tools from Qsound to generate the audio/positional data and the Q1 chip to do the DSP/Filtering, etc.. recreating that Qsound 3D effect over regular speakers using a regular amp.

This is the reason why the FPGA solution if implemented correctly, will work the same as the original QSound Q1 chip. @Darksoft, working with @jotego, has already tested and verified that the FPGA solution works exactly like the original.

So as long as you have a stereo amp/speaker setup you should notice the Qsound 3D effect. Will it sound better? That's up to the listener :P

With so many cool multis out with the LCD panels, is someone out there planning on making an LCD condenser (so only one is required per cab)? If so, I’d happily purchase one before I mickey mouse one together.

Much like the kick harness condensers:

Darksoft needed to laser-etched the Altera chip as "DARKSOFT - Q1" :D

That's a nice idea :)
Derick2k said:
The beauty of this plug-in module is that if the original Q1 chip fails, you can easily plug in a replacement. @Darksoft thinking ahead just in case, thats what I call added value :thumbup:

Yeah, you could do that, but for now the FPGA is only available for CPS1 Multis.

I agree. The debate regarding the Qsound amp's value in a fully spec'ed Qsound setup does rages on, albeit v v quietly. I think the real difference is that 27-30 years later we've all been spoiled by multi-speaker surround formats such as Dolby Digital, DTS, 7.1 setups, and into Dolby Atmos and beyond into modern day. None of us are going to be impressed by the two speaker stereo 3D effects that Qsound produces even if we can detect the difference. Thus, a fully spec'ed Qsound setup would have the same impact to a person living in today's world that a Hustler magazine would have on a person with a PornHub subscription.

The point is that no one is getting short changed by the FPGA chip. It is much ado about nothing. It was just a sourcing problem that was solved through additional development. As long as you have the multi that is all that matters.

I agree with what your saying bro. My point is that some people are getting all worked up trying to get these amps and speakers thinking they need it for Qsound to work when you do not.

If you trying to get them to complete/replace them in an original cab, that I understand.

The original amps and speaker are tuned be more bass rich if anything. Think of them like what Beats tries to do for headphones in a sense.

Qsound does work though if properly executed. You can definitely hear the difference in the sound staging/presence vs normal stereo. Obviously wont beat todays implementation of surround sound with multi speaker systems with proper mixing, etc..but its still a nice effect.

Awesome, thank you!

For anybody else looking I found the Street Fighter 2 manual here: https://www.arcade-museum.com/game_detail.php?game_id=9814
 
My Dynamo HS-5 cab is a stereo cab with a Q-Sound amp inside there. The 3D stereo effect is more of a "hey, did I hear something over my shoulder?" type thing and not the full-fledged 3D amazement that modern surround-sound provides.
