Hacking [Discussion] Install DS Profile exploit with Download Play?

[dicamarques]

Since the DS download play titles have to be signed to run on the 3DS, it seems as others have suggested the best method would be using an already signed title and then exploiting a vulnerability in that to execute the needed DS code. While possible I don't think many would be interested because the DS cards are so cheap and we already have the web browser as an entry point. However it does sound like a cool project.

A cool project, but I can't seem to remember of any download play that uses save data or can have data input (like bangai-o (it's not a demo)) so there no way to run the exploit (I guess)

I thought the same originally, however download play titles usually have a strong multi player element to them so the target would have to be the communication protocol between the two games. That would also mean having control of the original game to send malformed data. I've been reading about some attempts and while it seems possible it hasn't actually been developed at all.

Did someone see the smeas regionfree hack? It uses ds download play (ds mode)

smealum region free hack relies on Download plays access to the ns:s service, which then is used to launch the game. I'm curious if this has any implications for accessing the DS profile.

No.
The profile is stored in mset savedata IIRC.

As for the download play thing, I think it was fixed with a certain DS fw version.

Yes but we are assuming that your 3ds has been downgraded to 4.5

DS fw, not 3DS. The stuff that runs on the DS and DS Lite.

Sorry but I'm not understanding, what has been fixed in a DS version?

The homebrew launching method over Donwload Play. That's why it requires flashme now.

From my understanding flash me patched the DS firmware so that it wouldn't check for signatures on download play and normal carts. That way you could run DS flahs carts

That was added later for the new DS fw. Early DS fw don't have this check.

If we were going to do this over Download Play wouldn't something like Desmume be better idea that an actual DS. That would remove the problem with the Firmware version.

But the server DS (the one that's going to send the file) can be any flashcart compatible DS or even emulate it with a PC if you have the proper WiFi device, the issue is the 3DS that's looking for those signatures and not letting homebrew to run.

Desmume cant have direct access to a wifi card to emulate a DS in local multiplayer (if thats what you mean for using the desmume)

I was talking about the receiving DS.

Any progress on this?

No, but it's now possible to install this exploit with the browser so no need to do this

Are you talking about this thread: http://gbatemp.net/threads/how-to-install-cfw-on-4-5-without-ds-flashcart-gateway.380878/ ?
Sadly, it doesn't work for lots of people. If not - please provide a link, thanks.
