Homebrew .3dsx firms?

[Knucklesfan]

Quick question GBATemp-ers, why do we need emunand? Seriously, if we can replace the booting process, why can't we install menuhax and make it run an emunand? Or just a copy of the 3DS menu? This isn't fixing =<11.1.0.0, but its at least allowing people with >=11.0.0-33 to use a CFW. Why do we absolutely need Arm9LoaderHax? So why not make them .3dsx files?

That's not how .3dsx files work /:

A 3dsx is just an arm11 userland executable and we need an arm9 kernel exploit to run CFW. All known arm9 exploits were patched in 9.2 that's why downgrade is needed.

Plus, even if you could run MenuHax like that (which you can't), you'd have little to no boot protection, meaning that if you brick while installing something to SysNAND, you're screwed. MenuHax only loads after the OS is loaded, while A9LH loads much earlier in boot.

We don't. A9LH runs so early in the boot process that we can patch the required checks before sysnand boots, rendering emunand unnecessary.

Menuhax runs within the home menu. It can't run until the home menu is starting. A9LH makes this unnecessary as the patches are already done by then.

Or just a copy of the 3DS menu?

I think there is a project to replace the home menu, but this would not provide any additional permissions, only provide a new front end.

allowing people with >=11.0.0-33 to use a CFW.

I think you're confused. CFW requires the arm9 kernel to be exploited in order to run. The exploits which allow this to happen either run through A9LH, or through a 9.2 exploit. You can't just replace things on >9.2 and expect it to work.

Why do we absolutely need Arm9LoaderHax? So why not make them .3dsx files?

If you're running on sysnand 9.2 then you can absolutely use CFW from a 3dsx. Luma, for example, provides a 3dsx loader which is launched by menuhax (or manually from the HBL).


I'm not really sure what question you are asking or what problem you are trying to solve here.
