Homebrew Clarification Thread - What is going on?

So according to what he did 15 minutes ago, Steveice10 moved "APT_SetAppCpuTimeLimit to do_hax".

What effect does this make?

This is just cleaning up the code.

Good. Easier to understand, easier to work on!

So, from looking at the code, does this patch memory or something? And what does it patch/do exactly? Is it to move some priveliges down so we can get to them? Man, I still have so many questions about that unfinished code!

Is this guy some sort of caricature?

 

[julian20]

Btw, I, @mid-kid and @TuxSH are making good progress

Nobody knows, because I don't know either.

On memchunkhax2?

 

[Tapri]

If i recall correctly, isn't part of their intention to try to get to the Shared IO (where NDS commands are located) after getting the arm11 IO under control? Or am i mistaken?

That's to get ARM9 hax.

memchunkhax goal is to access AXIWRAM by mapping the AXIWRAM to userland memory to rewrite ARM11 kernel.

Will memchunkhax2 ever require the browser to access a URL like gateway does with launcher.dat or am I fine with having menuhax and a non accessible browser on 10.1?

That should work.

No need for browser. It is in the form of a .3dsx

I might not make sense, but how would we re-write the ARM11 kernel?

 

[dankzegriefer]

How would we re-write the ARM11 kernel?

By putting it into RAM the GPU can write to. Thus you can exploit it and modify it.

By mapping the ARM11 kernel RAM to RW in userland memory.

No. You can't move Kernel11.

That makes sense; thanks!

So, while looking at his code, I noticed at the very end it said "Press start to exit" Does this mean they plan on running homebrew apps in kernel? What would that do if we can't launch sysUpdater? Are they planning to make an app for it?

It's going to be implemented in libkhax. This 3dsx is mainly for debugging purposes.
