Homebrew [Request] Launcher.dat Chooser

Be honest tho, are you human?

He's asking all the right questions... and with that COD: Dogs mask... I'd say android.

So, I was coming back to tell you I have found ctrulib is usable from spider, BUT extremely difficulty so.

just fyi, you can run code that uses ctrulib to run under spider. the main thing is you need to somehow clean up spider (kill threads, close handles) and figure out *where* to put your code (on 9.2 and below you can use rohax to remap everything the way you want, but on 9.3+ you're limited to taking over a CRO).
there's code in ninjhax that cleans up spider's environment, but some of it relies on having rohax.

tbh, i think a better solution than this would be :
- on 9.3+, takeover an existing app from spider so you can just copy code over its .text with gspwn (should be pretty easy, see regionthree for an example of how to do this)
- on 9.2 and below, use the later stages of ninjhax to do rohax, clean up spider and use hb service to run 3dsx files.

neither of those things should be too hard, would just take time basically. i can guarantee that they're better than making a spider-specific "library" though.

in any case, good luck.

As explained above, it'd be difficult. Each binary needs a JavaScript payload to be launched from browser. An example of this is the browserify tool inside of spider3DStools. It generates a payload for binaries. Now, to implement something like that in a webpage so as to allow people to type their binary's name, and generate it quickly before executing seems a bit far fetched.

That actually exists. http://dukesrg.no-ip.org/3ds/
But I think he was talking about through the profile exploit, since he mentioned Palantine and Pasta.

A working trick, at least I think it would work, would be a program installed on the home menu that can rename delete/rename a file on the SD Card.

That way, you would choose a name for several launchers hardcoded in the app, for example :

CFW : CFW.dat
Gateway : Gateway.dat

And when you would choose "CFW" in the app, it would delete the actual "Launcher.dat" file then copy/rename "CFW.dat" file to "Launcher.dat" one.

If you would choose "Gateway", it would delete the actual "Launcher.dat" file then copy/rename "Gateway.dat" file to "Launcher.dat" one.

Then, like everytime, you would just need to run the DS profile exploit to launch either CFW or Gateway without having to access/swap the SD card.

Could just be a text program, displayed like that :

"Launcher.dat" Manager
1 : Copy "CFW.dat" to "Launcher.dat"
2 : Copy "Gateway.dat" to "Launcher.dat"
3 : Exit

Of course, I know nothing about coding but seems pretty simple, as access to SD Card should be possible, or else, cia installers wouldn't work.

And I would definitively use such a program, rather than switch SD Card for CFW and Gateway.

BINGO!

dude, if you can pull it off I'll have eternal gratitude towards you and your family for decades to come

That seems possible using Sudokuhax, which is the only way to run homebrew without first booting into a CFW.

Someone could create a DS homebrew (using the latest version of libnds) that does exactly that, plus (re)installing the correct MSET exploit

If you go doing that, you might as well just use the usual multi roploaders...

I don't think it's required to be able to run this homebrew without a CFW/Gateway. I rather thought of a homebrew you would install on both, CFW and Emunand for example, when you want to switch from one to the other. In my idea, it's basically just to avoid to use several SD Cards (or to remove it each time, then rename the launcher, then insert it back).

But yeah, a DS homebrew could even be better, as you can run them on sysnand directly and because you might need to reinstall the MSET exploit.
