Hoi

i recieved yesterday my DUO-RX system (with a normal Pc-Engine Pad (but i knew that before the sale) (payed 105 Euro with shipping from hong-kong and 7 Euro taxes and with a 220V adaptor and 2 mint new games (cd's)
(Prince Of Persia and 1 other)

First thing i did was try it out.
Conclusion:

Picture is Black and White on TV

Now i found some info on the ned for doing an RGB mos on pc-engine machines but there is no descent DUO-RX explanation.

What i did so far:

I found a place (like on (www.gamesx.com/rgbadd/rgbturbo.htm) to place a Male DB9 connector (pulled it out from a broken SMS II system, i now at the point of making the DB9 (Female) to SCART (AV) for RGB cause as far is i understood i have to take the rgb right from the DUO-RX videochip.

but now i'm stuck.

Where to solder the wires (R) (G) (B) to on the DB9 Male (on what pin numbers) and how do i solder the Sound to the DB9 Male (where do i need to get the wires for sound to the DB9 and on what pin numbers.) on the PC-Engine.

Other prob is.

The cable i bought a Female to female 10 feet cable (yeah in case  i @#%$ up i have a sprae female) i disassambled a old Scartcable.

No i'm stuck (i can't read electro diagrams)

SO:

Blue comes from pin 51 of the videochip
Red comes from pin 49 of the videochip
Green comes from pin 47 of the videochip

And i need to lift those pins from the PCB

Now the Wires from inside the DUO-RX to the DB9 Male

Male DB9:

1 2  3 4 5
.  .  .  .  .
 6 7  8 9
 .  .  .  .

Let's say i connect

1 to nothing
2 to Left audio
3 to GND Sound
4 to Right Audio
5 to Nothing
6 Red
7 Green
8 Blue
9 GND Fast Video Blanking




Then on the RGB and DB9 Female


 RGB                         DB9 Female
-----                       ------------
2 Audio R                   pin 4
4 GND Audio               pin 3
6 Audio L                   pin 2
7 Blue                       pin 8
11 Green                   pin 7
15 Red                      pin 6
16 must then be
connected to pin 21
of the scart with an
100 ohm resistor)
18 GND                      pin 9
---------------------------------------------------
Pin 20 Composite         pin 1
         Video Sync
---------------------------------------------------
(I'll use no Composite video sync, cause i'll only play on TV and not on monitor)
So dunno if that is needed or i can do it, but does it do something ???)



So can anybody confirm this works on a DUO RX system

So anybody can help me out and correct some stuff

hi,

wow. you are doing some serious stuff there...far beyond the capabilities of anyone who posts here.  i suggest you try posting at www.magicengine.com forums (i don't know if anyone there can help you).  you best bet, though, is to send a polite email to the guy who runs gamesx.  as far as i can tell, he is your best bet.  good luck.

 

did you try it on another TV? my big screen sometimes decides whatever is coming in on AV is B&W...
