About Nintendo's Duel Screen handheld console

I'm keeping this out of the DS emulator thread because this has more to do with the console itself.

So this thing is a handheld console with 3D graphics?
How powerful is it? More powerful than the PSX?

Is there any documentation available? I haven't seen any.

Thanks. Although I wish there was a more detailed spec listing.

Hypothetically it seems possible to emulate the DS at full speed on todays 2GHz PC's with an average quality DX9 video card; judging from the specs.

Personally I would like to know more technical info so I could make a better judgement.

Multi-core CPUs will definitely make it quicker to emulate because of the co-processor.

euhh i dont think GameFaqs is a very good source for info.... that review gives the Nintendo DS a 10/10 out of ten in almost everything...

just take a look at this...youll be laughing too

Graphics
The DS can render full 3D graphics, and can easily handle cel-shading. The graphics are slightly superior to that of the Nintendo 64, but games like Spider-Man 2 prove this theory wrong, as this game looks to be Sega Dreamcast quality. The major difference between the DS’s graphics and N64’s graphics is that DS has no texture filtering. This basically means that you may see little squares with different colors all bunched up next to each other without any real transition. The DS can display 3D on both screens at once.

When playing GameBoy Advance games, you may notice a difference between playing on the DS and playing on the GBA. The games look much better on the DS! This is because of the higher resolution on the DS, and expansion of colors. Games looks astonishingly more colorful, and sharper as well. Yet another reason to make the transition from GBA to DS.

9/10
....does he really know what he's talking about :???:

Not necessarily. I have a multi-CPU system, and it won't play any emulation any faster than a single-CPU system unless the emulator was designed for multi-CPU systems. Multi-core is a very similar concept. The only way that you're going to get a speed boost from multi-core is if software design changes radically - designers need to realize that they could be doing many tasks in parallel rather than serially. Then again, until HT came around, there was absolutely no reason to do so on anything other than server systems (Who else would buy an expensive multi-CPU system?).

One of the things that multi-core would do right now (today) is allow people to compress videos into xvid format while at the same time playing Half Life 2 (assuming that IO time is small and the user has plenty of RAM). That's about the extent of it with today's software design methodologies.

Oh, and you may also have to buy two licenses for Windows with a dual-core CPU due to licensing (this is still being worked out IIRC) just like all us other folks with multi-CPU systems foolish enough to run Windows (Professional does it for XP, but future licenses charge per CPU).

What he is saying, if you actualy read the statement, is that the DS sould be easier to emulate on a multi threaded/cored system because the DS itself is parrallel in nature.
I rather think you missed the point.

Uhh.... no, MS have already said you don't.

As I recall, there are many gaming consoles out there that utilize co-processors (COP0, etc.). Admittedly, this is a wild guess, but I suspect that emulation of such is serialized atm. What specifically about the DS is more parallel than, say, a PS1 (utilizes a main CPU + a co-processor CP0, just like the two ARMs used in the DS)?

MS decided not to charge per CPU? That's good news... :) Then again, I stopped paying attention a while ago when I started focusing on OS' that don't charge a bundle extra for a multi-CPU system.

Okay I'm going to shed some light on the matter with the duel processors. The DS as two processor a ARM7 and a ARM9. The ARM7 is the same one found on the GBA and is the only processor in use when playing GBA games. The ARM9 is the second processor, I've heard that this processor is older and documented. If your keeping up this the emulation shouldn't be hard(like PS2). The biggest issue would be backing up games, there is some random thing going on with the DS, makes it really hard to get the image. Any info you could possibly need is at the dsdev.org and look at the forum.
