Home Arcade System

is this common practice? I’ve never heard of it before. I have a similar interference issue with one of my superguns.

Anyone want to go into detail why there are 2 different ground connections for us newbies?

@8bitforlife - I fear this might be due to ground loops/home wiring issues. Try to connect PSU's signal ground (marked GND/COM) to frame ground (marked FG).
 
Do you know how severe the impact to picture quality will be using a SCART to S-video convertor
It's hard to say for sure, will probably be different from arcade PCB to PCB (with some worse than others).

I don't know when this will come to fruition though so for now I just want to try and run things through the HD TV to save space.
I totally agree and support this statement!
This is why you should abandon the HDPVR setup you have now and invest in a xRGB mini or OSSC. ;)

Both the xRGB mini and OSSC will accept SCART output directly from the HAS and spit-out a single HDMI you'll connect to your HD TV.

*Beware the "strange" syncs you'll get from an OSSC (its a line doubler not a sync rate changer) however...
Some HDTV's will only accept a perfect 60hz, to which you'll add a iScan DVDO VP30/50/50pro if that is the case (but just on the boards/consoles that require it, because yes it will also add lag). X/
xRGB mini is more of a P'nP solution for sure, but the quality against a finely tuned OSSC on a 4k its no comparison (the OSSC's 5x 1600x1200 4:4:4 color space mode wins).

I might of figured it out finally but opens up more questions. If i disconnect my audio 3.5 cable from has the interference goes completely away but then i cannot use my speaker setup i specifically bought for supergun. Would what you suggest i do or does your suggestion fix this issue?
How are your speakers wired up? Need to know every device from the HAS to the speaker. You have a ground loop in them
well the 3.5 goes to a amp with a rca converter and that amp goes to speakers with speaker wire (one speaker is powered and has a connection for the other speaker the amo plugs into the powered speaker). I had that shity retroeltronik super gun same setup except was rca to rca and no problems. So im going ro try a new 3.5 cable thats shielded. Now if i hook my hdmi to my computer monitor which has 3.5 out i can use my speaker system with no interference but i dont usually use my has on my monitor because its mainly for my ps4.

@8bitforlife - definitely worth trying the ground loop isolator, it's inexpensive. Have you tried to join GND with FG on the PSU? If you do, make sure you don't touch the PSU cage and audio/video cable at the same time (when they're powered on).
 
@jassin000 thanks for your help, I was leaning towards the OSSC anyway and now it sounds more likely that it is the way for me to go.
Just to make sure it's clear, the OSSC is simply a "video converter" in layman's terms*, it doesn't play any games. So you'd still need some kind of supergun to play CPS2 games.

As an example, your chain of devices on the video side would be like:

CPS2 A+B → HAS Supergun → 8pin mini din/Scart Cable → OSSC →HDMI Cable → HD TV


* It's actually an upscaler/line doubler.
 
CPS2 A+B → HAS Supergun → 8pin mini din/Scart Cable → OSSC →HDMI Cable → HD TV
Hopefully!
If he is unlucky/uneducated with his choice of HDTV however, It could end up being like...

CPS2→HAS→8pin mini-din SCART cable→OSSC→HDMI cable→iScan DVDO VP30→HDMI cable→HD TV

I just want to follow up and say connecting fg to g on my arcade supply absolutely fixed my interference issue. Spot on RGB!
 
Long-time lurker and first time poster chiming in!

I was lucky enough to get my hands on a HAS 3.1 from the previous batch, and have been enjoying it immensely. I recently bought an AvP B board, too, and would like to play it with a few of my mates.

Unfortunately, Mike is out of 3P4P adapters, and the minimum order size from OSH Park is 3 pieces. Would anyone else be interested in buying an adapter from him, so we could meet the minimum order size?

Thanks!

@dr_myslihiiri From Osh Park will come assembled aready or just as a board ? Cheers !
As @Sp33dFr34k already mentioned, the PCBs come from OSH Park unpopulated. However, it was my understanding that if Mike gets enough orders to meet the OSH Park minimum, he would build the adapters for us. (Please correct me if I misunderstood you, @RGB.)
 
That is correct, OSH Park minimum order amount is 3pcs, so to make it cost effective it will be best to find buyers for the remaining adapters. I'll also upload the design to OSH Park and make it available for people to order.
 
Well, I'm looking at the following which may help with your minimum order:

1x HAS
2x Saturn Adapters

Since the Saturn adapters say they do CPS2 6-buttons, would I still need the CPS2 Kick harness? If so, then 2x CPS2 Kick harness.

1x 3P4P adapter and 1x CPS2 3 and 4 player adapter.

And finally, I want to use and OSSC and F3 board, so I guess I need one of the following:

HD15 adapter PCB or 8pin mini DIN to HD15 adapter PCB, but I'm not sure what the difference would be. I have an extra VGA cable, so maybe that is the answer? But, I'm still hoping you incorporate some sort of fix in the next HAS to avoid the need for this! :P
 
Asumming @RGB will make other batch for the follow prdoucts ... i'm in for :

+ 1 x 3/4P adapter
+ 1 x CPS2 Player 3 and Player 4 harness for the 3/4P adapter
+ 1 x Konami Player 3 and Player 4 harness for the 3/4P adapter
+ 2 x Saturn adapters (if will have it on your schedule - hope will be available also)
