[REQUEST] DS to Wii connector

[REQUEST] DS to Wii connector You guys may know the things as Super Gameboy (GB to SNES), Gameboy N64 Expansion (don't know the actual name) (GBC to N64) and Gameboy Player (GBA to GCN). And now I am looking for a simular Homebrew Application that connects the DS to the Wii and shows the DS screens on the TV screen. And your DS is the controller (like you know from Pokémon Battle Revolution). It becomes in handy if I don't have a camera to record screens from DS. I am not asking for Emulators, ROMs or some piracy, just this Homebrew App, which I can simply start it in the Homebrew Channel, connect my DS to my Wii and play (and record, but by DVD Recorder can do this).

You can have a DS cartridge like this one : [www.youtube.com] and can send to another DS and act as a download server. Instead of sniffing packets (which will probablly be encrypted), or dissassembling the wii channels that use IOS calls (we don't seem to know how this works for now), why can we take the DS Download server cartridge and dissassemble the DS code to see which frames are sent to wifi (gbatek seems to have covered a big part of the wifi communications of the DS, and also the DS dosen't have IOS or such hidden functions) and replicate these with the wii (thats the part I don't know how to do it on wii : sending raw frames without a wireless router alias ad hoc networking)

That should give us an hint.

The linux build doesn't work, but this is only because the program can't always process received packets, in the timeframe required by the official WMB client.(Other processes may be executing, ect) There's also Juglak's NDS WMB Host. These could be used as protocol reference, as well as NDS Tech Wiki, and gbatek. Reverse Engineering Nintendo Channel will not help you find how to send/receive raw packets: WD has iotctls for sending WMB beacons, WMB data frames, and scanning for connection/reply frames from DSes. Nintendo Channel uses only those ioctls, no others.(Other than WD_SetLinkState and WD_SetConfig.) The WD WMB ioctls can't be used without the correct configuration. A proper ioctlv dump containing ioctlv 0x1004 is needed to use those ioctls: with all ioctlv 0x1004 parameters, first 2 are u32, the third and last is the configuration buffer.

Not completely true. To hack is to change code or add to code on the system but if we fake a signature there is no need to hack the device.

No, fake-signing WMB binaries is not possible: Nintendo uses an equivalent of memcmp, not strncmp.]]> yellowstar Ideas, requestsThu, 11 Jun 2009 22:21:58 +0200 http://forum.wiibrew.org/read.php?26,13158,19910#msg-19910 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,19910#msg-19910 pinball Wizard Ideas, requestsTue, 09 Jun 2009 02:17:28 +0200 http://forum.wiibrew.org/read.php?26,13158,19837#msg-19837 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,19837#msg-19837 SifJar Ideas, requestsMon, 08 Jun 2009 17:57:57 +0200 http://forum.wiibrew.org/read.php?26,13158,19770#msg-19770 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,19770#msg-19770

Anyway, in all seriousness, just shooting here, could we use a packet sniffer to see the communications between Wii and DS, then try and replicate these communications with a homebrew DS app and a homebrew Wii app, then take it from there? This is just a vague sort of idea, I don't really know what I'm talking about here, just know a packet sniffer can be used to watch communications over WiFi, and download data transferred or something. (Read about it for DS Demo Capture, but decided it was too complicated for me to actually try ;))

We already know the data that is sent to the DS. We can even setup our own "demo download station" with PC software and a wi-fi card. See here:[www.pocketgamer.co.uk] the only issue is the makers of the software doesn't make it an open-source app. It is possible to ask around and get the information to see if they would give it up and such.]]> pinball Wizard Ideas, requestsMon, 08 Jun 2009 03:05:05 +0200 http://forum.wiibrew.org/read.php?26,13158,19761#msg-19761 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,19761#msg-19761

When playing a game nothing in the game is telling the DS to communicate with anyone, therefore even if you have the wii setup to "listen" for the DS, it will never recieve a signal because the DS isnt giving one out.

The only solution I could see for this is to get a homebrew app on the DS which launches the game in your SD slot + sends a sound+vid signal constantly. The problem with this however, as was stated, is that the DS probably won't have enough ressources to power that kind've thing on top of the game without some serious performance issues, since all ressources are geared toward powering the game. Then you'll probably need to keep your DS plugged in the whole time because that will eat up your battery like a mofo.

I think it's definately doable... worth it? I'm not so sure about that.]]> ozzadar Ideas, requestsSun, 07 Jun 2009 23:02:44 +0200 http://forum.wiibrew.org/read.php?26,13158,19693#msg-19693 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,19693#msg-19693

Your assumptions are correct. It is communication between 1 DS and 1 Wii game.

That is absolutely correct. The DS acts like a client to receiving such games. We could in theory monitor all communication from the Nintendo channel with a custom IOS to understand the server communication but in reality there are already servers for the PC world that will let you send stuff to your DS. The communication part is easy, what our biggest problem would be is that the DS will refuse to accept anything that is not signed by Nintendo so we would have to find out how to fake signatures.]]> pinball Wizard Ideas, requestsSun, 07 Jun 2009 15:26:49 +0200 http://forum.wiibrew.org/read.php?26,13158,14940#msg-14940 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,14940#msg-14940 bushing Ideas, requestsMon, 20 Apr 2009 14:11:16 +0200 http://forum.wiibrew.org/read.php?26,13158,14923#msg-14923 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,14923#msg-14923

And even if we could (seriously, we cant -- Its technically impossible) the functions used would be buried in the Wiis SDK which we dont have access to.

We may not get the source code in it's raw form, but we will see a functionally identical assembler code.
That will also include anything required from Nintendo's SDK, because it is statically linked into the channel.

Now all that is needed is someone, who can understand disassembled power-pc source

Is the reason for the performance loss because of that it requires a lot of power from the DS to stream?

It is because it requires any power to stream. Games are free to utilize the whole power of the DS. There are no additional resources left.

Unlike Windows for example, the software architecture on the DS, or the Wii and most consoles is rather monolithic.
Games are used to run alone and have all resources just for them. They are also not used to cooperate

Hm... I don't know how powerful the wireless connection between the wii and the DS is, but if it is powerful enough video and sound could be streamed from the DS directly to the wii.
If this is possible no emulator would be required.

The bandwidth between the Wii and the DS is the least of all problems.
You have to make the DS stream it's audio and video, while still running a game. That is impossible without a major performance loss. And even getting the DS to do so is a hard piece of work.]]> daniel_c_w Ideas, requestsMon, 06 Apr 2009 13:38:25 +0200 http://forum.wiibrew.org/read.php?26,13158,13446#msg-13446 Re: [REQUEST] DS to Wii connectorhttp://forum.wiibrew.org/read.php?26,13158,13446#msg-13446

Because neither Nintendo, nor anybody else releases the right hardware.
The Super Gameboy and the GameboyPlayer are no emulators. They are the full hardware, minus display and input.

Software emulation of the DS on the Wii is doable, but in early development.

Just an idea here; have a homebrew app that connects through the router to a server on your computer, then have the same thing with the DS. Have the server link both the DS and the Wii, and there you go.

Don't know if this will work, new to the Nintendo homebrew scene, though I've been in the Sony homebrew scene for years.

I don't get it.
So I have to connect my DS to a wireless router, to my server, to my computer? :-S
