NEW CPS1 helper board (V1.3) for Marqs HDMI board for CPS1

[mathewbeall]

If any of you are just going to harvest the u-shaped headers off your old helper board, and JUST need the new board - let me know. I have 16 of them. I will let you know if/when I am able to source the male headers.

New firmware has dropped. Tested on my setup and confirmed that audio from CPS1 and CPS1.5 switch without issue:

That was fast! The real question is if I can wait until the weekend to try this out, after I get the right angle adapter marqs suggested?!

I probably should - as I also need to install the dual frequency oscillator kit from Mitsu!

FWIW, in my Jasen case build out, I was able to get by without a HDMI adapter, just a cable with a low profile and less bulk:

Ahhh - i see - just directly out to the TV, no intermediary adapter?

I ended up using this one , to the neutronics in the front.

I used this right angle adapter with the Monoprice cable.

I just wrote the firmware over to the CPS2 Digi AV board - validated all is still functional - firmware is 4 years newer!

Amazing news! Thank you very much for sharing.

Both of my Aliexpress USB blasters refuse to work. Not sure if it’s bad hardware, wrong software, operator error.

Mind if I ask what USB blaster hardware/Quartus version you are using for the firmware flash?

 

[mathewbeall]

I used this one.

I will have to look at the quartus version when I get home.

Thanks, am getting desperate enough that even the officially licensed ones for $US100+ were starting to look attractive, this one is a much better price point.

Im positive its some combination of Quartus version, Driver Version, and Hardware version - harder than I expected

 

[mathewbeall]

I will check when I get home later today - I might even have the install file for what I have installed, and can send it over.

 

[mathewbeall]

Here is the version that I have.

 

[mathewbeall]

and I do have the installer file still as well - just let me know.

Thank you very, very much! - I was stuck in that special troubleshooting place with untrusted hardware and untrusted software and untrusted device and no way of knowing which of them was the problem. I really appreciate this.

Intel are weird with their software; a few months ago it was like a state secret and only the current version was available to download. But when I check now every version as far back as 17.0 is available for download.

For anyone else that reads this the (currently working) download link for 20.1.1 is here - get it before they change their minds again

Just finished installing the dual oscillator board as well as the qsound hookups for the new 1.3 helper board - and amazingly, after troubleshooting a loose CSYNC wire, everything is working!

Now I have to get it all back in the jasen case and buttoned up and make sure everything still works...

This is as far as I got tonight. That right angle header doesn't sit flat as stock cause of the IC on the other side. Cut the legs down a little and was able to solder it in flat. I was able to get it the board in and solder 2 wires tonight. Gonna do the rest tomorrow morning.

 

[mathewbeall]

yep - I had to cut the legs down as well.

I posted this on Schmups as well, so if anyone can think of why this issue is persisting, I would appreciate any recommendations. Thank you.
I need some help identifying what may be causing Static sound on the new CPS1.5 adapter board for the CPS Digital AV with a Darksoft CPS1 multi. All regular games plays and sounds fine and Qsound games plays fine; just the audio is mostly static. I can hear the game audio playing but not much; possibly interference? I had a fellow AP member verify the wiring was correct. Does the 3-wire going from the Multi to the adapter board have to be shielded? I don't know what else would cause such a sound. Any ideas would be greatly appreciated.

Summary
Regular Games: Plays and sounds fine through HDMI and through JAMMA.
Qsound Games JAMMA: Plays and sounds fine through JAMMA
Qsound games HDMI: Plays fine, but audio is static. You can hear actual game audio playing so something is coming through.

Firmware programmed correctly. Shows March 2, 2024 and Version 0.93.

 

[mathewbeall]

So i had this exact same issue @raynex but I routed the wires a couple of different ways and eventually got rid of the static. I wonder if using a shielded wire for the qsound would be better?

 

[raynex]

Marqs replied back to my post and recommended using a shielded cable with the shield grounded on Both ends. I initially tested a 3 core shielded cable with 1 end grounded, but still had static, so I followed what Marqs said and voila, no more statis. Everything is crystal clear. Photos below shows where I grounded it. The shielded cable should be required for the install since interference can vary from person to person. Mine was realllly bad. I posted the resulting video in Discord under the PolyGame Master Arcade, if anyone wants to check. It's too big to upload here.
