is it able to download software to steam demos from pc per w-lan?
in japan, there are some demo spots. can i download somewere the software from this spots?

I think these spots just upload a binary to your DS.. I don't think it will be technicaly possible to stream larger binaries to your DS ...

and why not? whats to stop you from uploading a full game via download play once we figure out how to send the signal?

Umm.. Maybe the fact that the memory can't hold all that data?

yes, you right. the ds only have 4MB. But i talk just about game comerzial demos.

Even if the RAM can only hold part of the game, what's to stop crackers in the large-scale copyright infringement scene from replacing Nintendo DS game card access code with Wi-Fi code to pull down the rest of the game's files using HTTP or CIFS the way they've patched GameCube games to read from the BBA rather than the disc?

Two things.
First, the 11 mbps WiFi connection is slow as it is. It fades compared to the speed of Ethernet.
Second, and this is the main reason, the DS does not have a slow-ass DVD drive it reads from - it reads from lightning-speed ROM. It depends on data to be available instantly. That's why you generally don't have loading times in cartridge-based systems. Trying to match the speed of ROM with a slow WiFi connection is impossible, and if attempted would result in your games playing exclusively in Bullet Time.

The DS may not even be able to get up to the full 11 Mbps - PictoChat, for example, only communicates at 2 Mbps.

Isn't the DS cart bus significantly slower than the GBA cart bus?

"generally" means N-Gage.

Not all games continuously stream things from the ROM, right?

The BBA in the GC tops out at 27 Mbps due to the speed of the bus it is on, but is used in 10 Mbps mode when streaming games, so 11 Mbps would be more than enough.

According to the 802.11 beacon frames I've seen the supported speeds are 1 Mbit/sec and 2 Mbit/sec.
That doesn't exclude support for faster speeds but you would think they would use faster speeds if they could considering how long it takes to load the download play code on to the guest DS.

But the faster the WiFi goes, the more the battery is used.

either way.. DS games were built to be sent in chunks.. when a part of a game needs to look at another part it just can't puzzle (for all I know) with pieces of a binary or anything... I highly doubt this'll ever come true

But, like Sandymac mentioned, they would use faster speeds for download play if they could. Sure, faster speeds may use more battery power, but it would get the download completed faster, which should ensure the same amount of battery power is consumed.

The simple truth to the matter is that NONE of us is able to get WIFI on DS to work at all.
