Nintendo DS - wanting to use PSone screen for top DS screen.

someday there will be a diagram with pinouts. I mean, it happened for the PSP...

Finally got reply from my e-mail, not good news though (his reply on top):

Sorry for the late reply. The DS does not output an analog video
signal, so it's not possible to simply wire it to a different screen
(like PSone for example). For s-video or composite output, you will
need to use a video encoder. For analog RGB, maybe you could get away
with using just a DAC and some extra logic to adjust the timing. If the
PSone screen only accepts PAL, that's another problem, as DS video runs
at 60Hz. At any rate, it's not a trivial project... if you don't have
much of a background in electronics, I think you will have a lot of
difficulty taking on this project.

I hope that answers your questions.

Oh well,so much about that. I guess you'll have to wait for a TV Tuner then.

more like a TV converter. A TV Tuner is for getting TV broadcasts, and into the system

I doubt there will be one, after all the DS technically has two screens (one is a touchscreen), so the TV pic would only fill 1/4 of the screen - be a bit small!

I was more referencing the fact that the thing for the GBA is called TV Tuner.

Anyway, since the DS is techinicially hardware compatible, couldn't it... Nah, that'd never work...

you're right, it wouldn't. Have you played GBA games on a DS? There's a border. The DS has a higher resolution.

And the TV tuner (used to watch TV) is an entirely seperate piece of hardware from the TV adapter. In fact, Nintendo are going to release a DS TV tuner in Japan.

As I recall, when I was researching before, the only tv-out add-on was a prototype from that company who went out of business in Hong Kong whne Sony went for them. The comments I read about the prototype were hardly flattering anyway.

It looks like you need to be a pretty major electronics geek to be able to make such a project work; way over the head of any level I will ever get to.

Are you talking about lik-sang?

Kyo - yes, that's the one. I couldn't remember how to spell it!

The only links on Google for tv out on a DS referred to Lik-sang. I read some reviews from prototype testers and they were less than complimentary about the visual quality as I recall.

If anyone was to develop one, and it was good quality, it could make for a nice little project; however it doesn't look likely, after all the DS has been out for a while now and no-one seems to have made a tv-out facility for the DS.
