Homebrew [Custom Launcher] Spider3DSTools released

[yifan_lu]

Will it dump it to a file on the SD card?

Yeah. mem-fcram.bin

 

[DarkFlare69]

Yeah. mem-fcram.bin

Okay. Thanks!

 

[rockthetemp123]

Anyone know if this works in Gateway mode? Not emmuannd.

 

[Shubshub]

Anything new in terms of Spider code.bin files? Haven't really seen much progress lately :/

 

[duke_srg]

You should really submit a pull request to the git repo for all of this.

Finally, here is my forked version. Will also add a VC injection ROP part source soon.

Just for a Laugh you should try and get 3dsx loading on >9.4 probably won't work out that well but hey its worth a shot

Guys could someone tell me how to get the code.bin to crash? I mean, after doing what i want to do, i need it to crash back to the homescreen...

What I usually do is attempt to load a very large value into buf.

Something like what?

 

[shutterbug2000]

I can't remember exactly. Try like 0x10000000

That'll cause a crash lol.

 

[AlbertoSONIC]

What does "svcSleepThread(0x400000LL)" do?

Doesn't returning 0 from uvl_entry function makes the 3ds to crash spider?

 

[AlbertoSONIC]

Doesn't returning 0 from uvl_entry function makes the 3ds to crash spider?

I don't think so, since this code freezes the 3ds instead of crashing spider:

#define START_SECTION __attribute__ ((section (".text.start"), naked))
 
// make sure code is PIE
#ifndef __PIE__
#error "Must compile with -fPIE"
#endif
 
int(*IFile_Open)(void *this, const short *path, int flags) = 0x0022FE08;
int(*IFile_Write)(void *this, unsigned int *written, void *src, unsigned int len) = 0x00168764;
int(*GX_SetTextureCopy)(void *input_buffer, void *output_buffer, unsigned int size, int in_x, int in_y, int out_x, int out_y, int flags) = 0x0011DD48;
int(*GSPGPU_FlushDataCache)(void *addr, unsigned int len) = 0x00191504;
int(*svcSleepThread)(unsigned long long nanoseconds) = 0x0023FFE8;
 
int uvl_entry();
 
int START_SECTION
uvl_start()
{
    __asm__ volatile (".word 0xE1A00000");
    uvl_entry();
    __asm__ volatile ("bx lr");
}
 
int
uvl_entry()
{
    return 0;
}

Then your best bet is corrupting heap memory as shutterbug2000 says

 

[Shubshub]

Just an Idea perhaps...

Would it be possible to have it Crash while attempting to load a game from the cartridge slot and then redirect that to the SD Card?

 

[AlbertoSONIC]

So, i just have to write 0x100000000 as buffer? Using SetTextureCopy command?

Would dereferencing a null pointer work? Like:

*(int*)0 = 0;

I haven't done anything with Spider3DSTools yet, so I wouldn't know. (Or would it just write 0 to the beginning of physical memory?)

 

[Secret Dragoon]

You could just arbitrarily write memory with zeroes or Fs. That'll most certainly get things crashing.

You should see if you can Inject something to show up where the Cartridges show up on the Home Menu that would be interesting

You mean i should write the fcram with zeros? Wouldn't that get the whole system to crash? I just want to get spider to crash...
