One of the easiest PS1/2 pads to hack are the PSOne pads:

I use two of them in my cab, works great with all my converters.

Viletim,

Your audio setup is much better than the one I used prior, which was to use the Taito on board amplifier along side the HDboxpro. The Taito on board amplifier doesn't like the audio from consoles, it distorts on high and low frequencies for some strange reason. The Dreamcast is especially distorted.

So I have a 50/50 thing going on right now. What I mean is, if I use my hi resolution AWSD cabinet with say Tekken 5 with the HDboxpro I get 480p resolution via the component cable from the PS2, the HDboxpro converts that to VGA (and does a good job). I have put 14db attenuators in the mix to stop the distortion but now the frequencies are muffled. If I use the SCART>Jamma set up, I get excellent audio, but I can't go above the standard 480i resolution, which looks a bit low resolution to my eyes. I want the best of both worlds.

So what I was thinking was if you could modify one of your boards so that the phono's were in fact inputs, couple that with the on board amplification that you have on your SCART>Jamma setup already. That would mean I could use the HDboxpro for 480p on games that support it and just use your little PCB to pass the sound. I would imagine this would work better than the current set up, since SCART buzzing won't be a problem. For 2D games where 240p is the best resolution possible, I will just use my current SCART>Jamma setup that I already bought from you. I like your work, so I thought I would ask. It is basically reverse engineering just one part of your current board so I thought it might be quite an easy task.

So in a nutshell. I would like another board just like the one I have, but reversing the audio so that the phono's are inputs and the amplified audio is passed via jamma to the speakers. The video will be bypassed through the HDboxpro, where 480p is the best resolution. Thanks for reading.

Richie.

@richie

why not just get a RCA audio to scart adapter? but one problem may be that your monitor may not like having anything connected to its low res (JAMMA) input (even if it's a blank signal) while using the VGA input.

[neorichieb1971]

I've never been able to put a scart and a component cable into my PS2 at the same time.

How about you use this: http://www.telly-leads.co.uk/scartadapter.htm for the RCA sound on the component cables into the magical red adapter from viletim -> JAMMA harness, and put the video from the HD Box Pro into your Wei Ya VGA input?

Running a VGA signal into a Tri-Sync always blocks out any RGBS signals on the JAMMA in my experience.

[neorichieb1971]

Never thought of that. Good thinking.

It will bypass the jamma video, because the jamma video has to be disconnected to go VGA direct.

[neorichieb1971]

It would obviously be better to have it RCA in through a dedicated PCB for the job. I'll purchase a scart adapter and see how it fairs.

emphatic's link was what I meant.

how does your monitor know what video input to use? (it has jamma and vga, right?) a switch? auto detect?

[neorichieb1971]

At the bottom of the AWSD base there is a VGA HD15 connector. Male into female. The cable part of it detaches and goes to the CRT. If you put a Dreamcast or any other VGA device into the cable you are putting 480p straight into the monitor.

If you connect that CRT VGA cable into the connector on the base of the AWSD, it essentially is getting the video from the jamma connector.

Therefore by doing what you have proposed, the video will go straight to the CRT directly, the audio will funnel through the jamma harness. Good job Viletim put SCART and JP21 on there, otherwise i'd be modding more crap. As it stands it seems like the trick will work. I will test it tomorrow.

Directly or through a converter ? Putting JAMMA voltage levels directly into VGA is not a good idea.

[neorichieb1971]

My AWSD is standard. However it does what it does, it does it the way its designed to be done.

I would imagine it takes 15khz and puts it through the VGA port somehow. If you disconnect the jamma HD15 and feed a proper VGA 31khz signal through the other side, it obviously likes that idea as well.

Whatever I do, the cab likes it. Its got more switches and knobs in that thing than Concorde.

If you saw my cab, you would realize its not just any cab, its a super cab.. The only thing missing is the cape.

[antron]

the genesis rgb cable arrived. my jamma modded genny 2 has neven been easier to set up. I used to have to make major adjustments from PCB video settings, and still had problems. Now it always looks great, has amplified audio, and I still get to use my internal hacked controllers, plug and play.

Awesome comment

I ordered a grey PS1 Scart cable off of ebay.uk, but they shipped me the cheap 3rd party black one. I called him out on it and he said the grey was a knockoff as well.

Anyway, can someone explain what the audio buzz would sound like? There is a buzz, but it's coming from the cab itself, not the audio. When I close up the cab you don't notice it at all...

Also, are the RCA audio jacks just plug and play? I couldn't seem to get any audio from them, but I can try another cable.

[neorichieb1971]

SCART buzz sounds like anything that you turn up really loud without actually anything coming out of the speakers. You just hear mmmmmmmmmmm droning on and on.

Grey scart leads are not always legit, but the official Sony scarts are grey (same colour as the playstations were back in 1995). I doubt you can buy a legit Sony one now anyways. There are no markings on the official one and i've not seen any difference between an official one and a good 3rd party one anyways. I remember having an official Sony scart lead once and it forced borders on top and bottom, had to cut pin 8 which sorted that out. If Monster makes one, you would probably be best served by it, but I don't think Monster make playstation Euro SCARTS, may be wrong though. If your paying less than £10 for one, its likely going to have the buzzing noise.

[neorichieb1971]

I tried using the HDboxpro with the SCART>Jamma to pass audio via a phono>scart adapter. It works brilliantly.

Video - PS2>Component>HDboxpro>VGA input of cabinet = 480p

Audio - PS2>Component>phono into scart adapter>SCARTtoJamma from Viletim = Great audio.


We already discussed the low res quality, which is quite magnificent. I just wish the pad hacks were simple to implement.


Thanks for the cheap workaround, its great.

[emphatic]

Glad it worked! Not too messy either.

if i wanted scanlines in my picture and wanted to do this:

dreamcast> extron emotia > to console/arcade monitor adapter
(vga) > (rgbs to scart) > scart input on adapter

will the picture be 240p? will the console/arcade monitor adapter be able to do this?
my monitor is tri-res.

thanks in advance for any assistance.

I thought the dreamcast was 240p with scart (at least some games are)

but yes, that would work.

+1 on ^^ these suggestions as both should be valid. According to Andy @ Ultimarc, not all DC's output @ 15kHz though. Personally, I've never had any issues running it in low-res, but my setup does differ somewhat.

here's a quick shot of my 360 hooked up to my astro with this adapter, I love this thing!!

pic is taken with my droid so it's kinda washed out in person it looks awesome.

and by the way, you'll need to move the jumper from jp2 to jp3 to accept the c-sync that is output by the emotia.

[drunkninja24]

Can the JAMMA connector on the bottom of the board be used to pass through video signals? I have an emotia connected to a Jammaboards adapter in the cab, and would like to connect both so I don't have to keep switching around the JAMMA connector when I want to play PS2 and 360. Would that cause any issues?

[slap_fight]

just confirmation that i disconnected a mod that i made to the cab's speakers and now the screen doesn't flicker anymore. i also fixed my super famicom. game on!!

There is a warning silk-screened on the board not to do this, so I'm guessing no.

the video and audio lines on that jamma connector are not connected to anything. there is only one way to get those signals in, the SCART/21pin plugs.

Yes, just connect straight to an amplifier.

In regards to the SCART lead buzzing sound, this is the sound of the video signal getting into the audio. It's caused by poor grounding - many of the cheap leads use only a single thin wire for ground while the official leads use a copper sheild.

The buzzing can be reduced or eliminated completely by making a good ground (and by that I mean the signal return path, not safty 'earth' ground) connection between the console and the adapter. It can be as simple as a good thick wire screwed between the console's metal sheilding and the ground point on the terminal block.

Hello,
received mine yesterday and tried it on my atomiswave with a pal PS2
To get it to work I had to :
1) unplug my stereo amplifier
2) use the white capacitor provided by viletim
3) plug the D1/D2 cable (the one hidden below the front door of the AW, it was unplugged and I couldn't get a good synchro, I plugged it back and then everything runs fine !! )

Now everything works very nicely, both with pal (50hz) and ntsc (60hz) signals !!
I'll do a few more hours of testing tonight with my saturn and snes
Thanks a lot to viletim ! Great piece of work and nice packaging

Have you tried? It's not as bad as it seems. Lemme know if you need any help

[neorichieb1971]

Someone is already dealing with the pad hacks for me, although at the moment he only completed the 1p with a namco stick PCB(PS1).

I want the 2p side sorted for Bubble Bobble and Tekken 5.
