How Feasible Would This Be?

    So, within the last month we learned that we can access more than we thought we could(game contents) Which in turn has allowed us to use Rom Hacks, or even adjust small things in the system menu.

    Then Smealum tweeted something. A User was able to edit the text in the system settings, which means he must have dumped it or at least was loading an external file over it.

    So my idea would be. Using homebrew to dump/load a modified system settings app with a DS Profile Exploit in it. Which in turn would allow us to do fun things.

    I plan on looking a bit into it myself. However I would like some opinions from the rest of the community. Since Im sure there are details that Im not thinking of :)

    Wouldn't you still need kernel access or a 9.2 or lower FW to run rxtools to downgrade the mset to an exploitable version?

    I'd assume so. But my thinking is, that you can just load it overtop of the existing files and take priority. Even if the version isnt exploitable. Since it will be reading different data(if that makes sense)

    I think I've read a post on Reddit about someone trying to run an older dump of the System Settings app overtop their current one using HANS. It didn't work. I'm not sure about a modified one.

    I feel like I've read someone else's post about Smea putting some sort of protection over that kind of change, but I'm not sure if I read that post wrong or not. If I find the posts, I'll link them here.

    EDIT: It seems someone JUST tried this half an hour ago. https://www.reddit.com/r/3dshacks/c..._observationexperiment_with_mset_downgrading/

    I've been thinking about this ever since I first saw the system settings in HANS

    You should consider contacting that reddit poster zeldafan pointed out and share findings.
    It looks like he has the files and just needs someone to test.

    Let us know how it works out. If I can figure out how to do it, I'll test it out tomorrow after I get home from college.

    So, not to burst anyone's bubble, but just because you have an exploitable version of MSET doesn't mean jack in the long run, all MSET is is another entrypoint, so really if there was any way to do anything interesting from it it would also be able to be done with ironhax, ninjhax, OoT3dhax, browserhax and menuhax entrypoints... So really there isn't any useful applications as you need one of those entrypoints to get this working in the first place, it would honestly just be easier to just use the existing entrypoints instead of making new ones to do the same thing

    No one said we where making new ones. In all of my replies Ive already stated im using the existing ones.

    Unless we find another kernel exploit (about a 0.0001% chance of happening)

    What you're trying to do is make a "new" entrypoint for 9.3+ systems using MSET from HANS right? Or did I miss something? Basically there really is no point in even trying as it won't amount to anything is what I'm trying to say

    Eh, personally I'm on a lower FW and already have kernel access, I'm just curious about this as an experiment to check the rigidity and boundaries of hans.

    There's a higher chance than that, I'm pretty sure some people have kernel exploits and haven't released them... No system is perfect so it's possible, all we need is a good reverse engineer who's willing to share their work (though I can't blame them for not wanting to share based on the community)
