Homebrew Homebrew Development

Kane49, I found your super secret exploit.

#include <arm11.h>
 
void _thread(){
 
    //p("THREADSTUFFONE");
    //asm("UXTB r0,r1");
    //p("THREADSTUFFBITCH");
}

Thanks, I've completed a CFW now.

Care to share it?

The only difference between 1.0 and 2.0b2 is the address they use. It looks like Kane49 is using the address 1.0 uses. The address I posted is from 2.0b2.
You can if you really want to actually cleanly exit from the arm11 privileged mode when your code is done and repatch the services to do what they were supposed to do.

My progress are slowed down by file size limitation of loader.dat, so sometime I go back to the beginning to search something to shrink the size.

Since baremetal arm9 homebrew seems dead, here is to you a little trick that can reduce a little file size and double graphic rendering on our arm9 enviroment.

/*
  Hint for an InitScreen() implementation
*/
 
#include "main.h"
#include "memory.h"
#include "draw.h"
 
 
int main(){
  int i;
  char * a;
  char * b;
  unsigned long topleftframe;
  a= (char *) TOP_LEFT_FRAME0;
  b= (char *) TOP_LEFT_FRAME1;
  if (a[0]==98) topleftframe= TOP_LEFT_FRAME0;
  else {
    if (b[0]==98) topleftframe= TOP_LEFT_FRAME1;
    else {
      draw_string("Arrrg... this should not ever happen!!!",0,0,255,255,255,BOTTOM_FRAME0);
      draw_string("Arrrg... this should not ever happen!!!",0,0,255,255,255,BOTTOM_FRAME1);
      return -1;
    }
  }
  draw_string("Hello!",0,0,255,255,255,topleftframe);
  return 0;
}

It works for me, please try it and let me know if it's another hole in the water like the touchpad state.

Where did you guys learned to work on that ? Could you guys send me a study site ?

You can give this a try. It loads your "run.bin" to 0x23200000. Don't know how picky it is with SD cards (it worked for me).

If you're lucky, arm11 is trapped too in this launcher and waits for a jump address

Ok, im am the biggest noob when it comes to 3ds hacking. But what does your file do and how can i use it on my 3ds?

If you want lo learn C programmig, start whit the Kernighan & Ritchie, and try to write some "hello word" programs for DOS or linux shell command line. If you like it, you'll find your way.

I've been reading this thread a little bit but fyi the Youtube App is a web browser limited to the youtube, it scores more on the html5 test than the built in browser. So theres already some html5 on the 3ds but not all of it.

It doesn't work on my 3DS. Looking with an hex editor, Launcher.dat seems crypted. Is it intended to be used with GW ROPLoader?

You can check my files in the 3DS_Launcher folder there is an example how to load files during the rop chain / Create a mini file system with kfs.py etc.
It also shows how to make all the areas executeable etc so if you want to do bare metal arm 9 stuff everything is in there.

I already noticed it. But with my little knowledge of ARM ASM it's a little bit too difficoult to understand. Maybe this summer I'll have time to study it.

Its in C and a tiny part in python ^^

¿What's new? I only see GPU svc coded as new

 

[profi200]

Some changes on libctru did break the source of yeti3DS. He updated it to work with the latest version.

The GPU stuff does nothing currently btw (i mean the GPU example of course).

Exactly! the Nintendo has already shown us the way forward, that is, it's totally possible to think in a browser that supports html5 ! would be cool to play on the 3ds's browser
