Homebrew I might have a theory on how to send the Homebrew Launcher via download play.

So... I've been recently datamining Mario Kart 7 in order to get CTGP-7 working. Throughout the file structure, I found the "ExtractedDownloadPlay" folder and found another CIA inside it. All the CIA is really is the download play version of MK7 that's sent to another 3DS's limited RAM. That then gave kind of an idea.

Yellow8's Homebrew Launcher CIA is WAY smaller than that CIA. So it kinda begs the question if it would be theoretically possible to send someone HBL by modding a game with DownloadPlay.

Now, I can't really test it out considering I don't have another 3DS, but I'm just presenting it out there just in case someone else wants to.

Of course, there's no guarantee that it'll work in the first place, but this was just some observations I had.

If it does work though, we could use this method to install other exploits on other people's 3DS's.

Anyways, what do you guys think about this? Do you think it's possible at all?

Not saying I found an exploit at all or even if this will work. Just giving my opinion on it.

There is already a thread about this. CTGP-7 doesn't send a modified dlp cia, it works because MK7 sends the course files from the main game romfs, instead of the dlp cia, which doesn't have to pass any sig checks. An exploit may be possible by sending corrupted szs files, or corrupted tracks. (Karthax hype :P)

    That's a relief to hear. Do you know what happened?

    @BakerMan, Any idea what happened? I hope that your brother's doing good.
  • BakerMan @ BakerMan:
    Well, from what I've heard from my parents, he had a seizure last night, perhaps an epileptic episode, fucking died, had a near death experience, my dad called the paramedics, they showed up, took him to the hospital, and he woke up covered in tubes, and started complaining.
  • BakerMan @ BakerMan:
    He couldn't eat until after his MRI, when he had a bomb pop.
  • BakerMan @ BakerMan:
    What matters now is that he's doing alright.
  • Veho @ Veho:
    But you still don't know what it was?
