Custom RGBHV cable for Saturn to Audio Authority 9A60

Does anyone know where to buy or how to pinout a custom RGBHV cable that connects a Sega Saturn to the Audio Authority 9A60?

 

There is no VGA cable for the Sega Saturn. The Saturn lacks H-Sync and V-Sync on the A/V Connector. You would need to tap directly from the DAC if possible.

Most VGA monitors won't support the Sega Saturn because most, if not all games don't support 480p output. The minimum requirements for most VGA monitors is 31KHz RGBHV (some can do RGsB Sync-on-Green) with a minimum resolution of 640x480p. I have read somewhere that the Saturn is capable of 480p VGA but it would require adding a VGA port.

All hope is not lost however. You can get a RGB SCART cable for your Saturn and a 15Khz RGB to 31KHz VGA converter like this one: http://www.ebay.com/itm/RGB-RGsB-RG...841?pt=LH_DefaultDomain_0&hash=item3a7c77e2f9

 

Hmm. One way seems to be assembling a project PCB with a SCART socket, VGA socket, power jack, and EL4583 chip.

I found this earlier and it looks like he's converting the signal as you described. Pretty interesting stuff!

Yeah if just using a CRT SDTV, get SCART to component. Such TVs don't support 480p anyway.

 

I'm using a Samsung UN32EH5000 that supports 480p over component. I can't tell if there's 240p support. Good thing about the AA 9A60 is that it doesn't rescale the source signal.

 

The basic check for 240p over component is PS2 playing a PS1 game.

 

Great idea!

Assuming that works, I suppose I'm still facing the issue of 15KHz vs 31KHz?

 

You can always try a SCART to HDMI converter like the one I use. It does upscaling unlike the RGB SCART to Component converter. The one I have uses a fully wired SCART socket so RGBS, Composite Video, and S-Video can be upscaled to 1080p at 50Hz or 60Hz via an HDMI cable. It also has a headphone jack and a Digital Coax audio jack.

If you don't have component cables for the PS2 (you should unless you use RGB SCART/RGB JP-21 Sync-on-Luma cables; I'd recommend the Gigaware Universal Component cable for PS2/3/Wii/360), you can still test for 240p with an old 240p console such as the SNES or Genesis/Mega Drive. The Saturn might even work.

Step 1: Plug composite (yes Composite not Component) cable into green Y jack.
Step 2: Plug an unconnected RCA cable into the blue Pb/Cb jack. Leave the other end disconnected.
Step 3: Repeat Step 2 for the red Pr/Cr jack.
Step 4: Turn on 240p console.

If you get a black and white image, scrolling or not scrolling, out of place or not out of place, your TV supports 240p Component video.

 

I did not see your post until after mine.

Once RGBS is converted to YPbPr Component, it will display even though the source is 15Khz. I don't know what would happen when using 31 KHz RGBS. I don't use those crappy SCART to Component converters which require tweaking the color pots for the best picture and have trouble with capture devices.

 

When RGBS is converted directly into component, 240p sources remain 240p.
TVs or capture devices that lack 240p component support won't work.

31 khz RGBS is non-standard. I've heard the XRGB Mini accepts it though.

 

I've heard that recording gameplay footage with these component converters only works with the Sega Genesis, even if you use the exact same capture device with another 240p console such as the SNES. Makes sense seeing a lot of these are advertised for the Genesis. Displaying them on a TV works fine though. Then again, this is what I've seen online and have been told by people who use them. I have no experience with them as I use a SCART to HDMI converter with more features, like upscaling and PAL/NTSC conversion.

I saw that the Toro VGA box supports 31Khz RGBS. The GameCube can also do 31Khz RGBS with a modded component cable or the GCVideo lite boards.

 

Heh. I know even less than that about capture devices.

It isn't like the type of conversion really matters. Whether the input is on a TV, converter, or capture device alike, needing to accept 240p component is a common factor.

 

I found this post about the 9A60 with the MVS. That's basically what I hope to accomplish with the Saturn.

If what they say in that thread is true, then you should be able to do the same thing with a Saturn. Just connect the composite sync pin to both H and V sync pins. If that doesn't work, another option would be to use a sync splitter to get get H and V sync from composite sync.

 

Is "composite sync" the same thing as 1. sync in this diagram?

 

Yes, I think so.

I'm not using an upscaler, just the Audio Authority 9A60
