Dreamcast to PSone LCD Screen?

DiscoSnorlax · Post by **DiscoSnorlax** » Sun Dec 12, 2004 6:08 pm

The other day I got a PSone LCD Screen, and I'd like to get it to work with my Dreamcast. When I apply power to the screen it lights up, and when I hooked it to a friend's PSone it worked for it (the screen went dark when the PSone was off, although I think it's supposed to do that.) So far I've managed to get audio but no video using a Dreamcast composite cord, a Playstation composite cord, and an in-line triple phono plug coupler (RS part #274-898)

Anyone know what I'm doing wrong? Somehow I suspect I'm going to have to get a spare Dreamcast and PSone video cords and crack open the housing on the console-ends of the plugs, remove the existing cables, and run cables between them.

Whatever solution comes up hopefully wouldn't need the VGA out, as some of my games don't like the VGA cord and refuse to play with it. (Anyone know a way around this? I'm tempted to try booting composite then hotswapping the cable...)

I'd rather do this without modding the Dreamcast or the LCD, basically a plug-and-play that'll work on any stock Dreamcast or PSone LCD Screen.

I plan to eventually try making something resembling the very back of the PSone that would mount to the Dreamcast somehow (any ideas?), just plug the 120VAC into the adapter, adapter supplies 120VAC to the Dreamcast and 7.5VDC to the screen, the screen screws to it like the back of the PSone.

ok the psone can take av in on that little head phone jack only if you bridge the grounds first.. to bad you can only get mono out of it.

but you can eazyly get anouther stario device cramed in there to get sound on it.

or you can get your DC rgb moded by gamesx.com and put that in to the psone screen.

Well, I "Borrowed" the cord that lets me hook my sound card to my stereo system, hooling video to right channel and hooking that to the AV-IN makes the vidoe work, but it interrupts the audio inputs. Hooking the sound to the left channel does provide sound, although I'd have to Y the l/r to one channel for that (I'd probably have a headphone socket pre-Y that sits over the stock socket for that I guess, to provide some way to get at real stereo instead of merged stereo.)

So exactly where /does/ the screen get its video from off the PSone, since it's obviously not the composite pins, and is there a simple/cheap way to convert the composite signal to the correct one? (Most likely involving cracking open the plastic covers on DC and PS1 video cords and soldering to the plugs' guts I suspect?)

The cable you are looking for has an end like this:

See how it has 4 bands or whatever you call them in the plug instead of the normal 3...

i think he wants to know how to take advantage of the PSones RGB in put.

well like i said earlyer you must make your DC have RGB out first.
then you plug it in to the Ps ones video slot on the corect pin. games X will have bouth pin outs to compare.

you could use the female from the screen on the dc
