So... Nintendo ds specs?

[Mendel]

Im considering writing an article on Nintendo DS...

So where would I find the most thorough specs for Nintendo DS.

So far this is the best I have found:
http://www.nintendo.com/techspecds

For example, the processors are officially listed just as ARM7 and ARM9 but no clockspeeds or any more info.

There is no mention of the graphics hardware, its features and speed.

Where should I find this info?

Oooh lots of good stuff - thanks to Vysez and Teasy; I've got some updating of my own to do now.

thanks for the heads up, Vysez
i could have continued visinting their site w/o noticing those.

btw, from the drunken coders docs, 3d/number formats

Vertex (v16)

1.3.12 fixed point number (1 bit sign, 3 bits number, 12 bits fraction)

UV (t16)

1.11.4 fixed point number.

Normal (v10)

1.0.9 fixed point (generally 3 of them will be packed into a single 32bit value) used for normals and lighting vectors.

Matrix (f32)

1.19.12 fixed point (matricies have a much larger range of available values)

the vertex and uv formats seem swapped.

DS has a nice touch screen to play with. This can only be accessed via the arm 7.

What sort of obstacle is this practically?

No, both processors can access to both screens but the ARM7 is used as a sound chip in the DS mode and is the main processor in the GBA mode.

So the drunken coders got that one wrong...


Sheesh this is a mess. How can I possibly gather an interesting list of features and specs if they're kept secret. Why would Nintendo want to keep them secret? Isn't it supposed to excite the customers with knowledge of its power? If they're worried about giving info to their competitors... well its no use, they can reverse engineer the thing anyways.

But am I supposed to open my console to know who manufactured the graphics chip? Photograph it and put that in an article and what happens? Nintendo sues me? It's not like they can hide it anyways...
