Hacking 3DS Injector

totally gonna try that now I guess we're limited to 4 characters correct?

Well, you could probably extend it to overwrite the actual version format string (the %d stuff), but I'm not sure if that might cause instability or crashing..

You can simplify the editing a little bit with:

  else if (progid == 0x0004001000021000LL) // MSET USA
  {
     static const char* ver_pattern = u"Ver.";
     static const char* ver_patch = u"A9LH";
     patch_memory(code, size, ver_pattern, 8, 0, ver_patch, 8, 1);
  }

I omitted the other MSETs for brevity.

dammit man! now i get warnings lol i don't like warnings..

Just do a dirty cast, I guess.

 

[chaoskagami]

Unicode strings aren't always 16-bit words. :/

 

[daxtsu]

Unicode strings aren't always 16-bit words. :/

Lower case "u" makes them 16-bit for GCC.

 

[chaoskagami]

Lower case "u" makes them 16-bit for GCC.

You're right, I just went into my man pages and looked it up.

Learn something new every day, I guess?

 

[Shadowtrance]

yeah that worked no more warnings! (i don't really know C btw haha)
static const char* ver_pattern = (char*)u"Ver.";
static const char* ver_patch = (char*)u"A9LH";

 

[daxtsu]

yeah that worked no more warnings! (i don't really know C btw haha)
static const char* ver_pattern = (char*)u"Ver.";
static const char* ver_patch = (char*)u"A9LH";

Such casts would probably make people scream in terror, but if it works, it works.

 

[Shadowtrance]

I just took a guess lol if there's a more correct way to do it, please do share.

You did say "dirty".

 

[Shadowtrance]

the warning i get btw without it is... warning: initialization from incompatible pointer type

--------------------- MERGED ---------------------------

You did say "dirty".

lol like i said, i just took a guess and it shut the warnings up haha

 

[daxtsu]

Here's some fun with the version string using this:

Spoiler

In code, that's:

     static const char* ver_pattern = u"Ver. %d.%d.%d-%d%ls";
     static const char* ver_patch =   u"ARM9LoaderHax %d.%d";

Someone can send me one for testing ?

I wonder if we would be able to differentiate Sys/EmuNAND strings, like RXTools did

Well a hacky way would be to have two loaders with different strings and let your firmlaunchhax code figure out what to inject based on if emunand is enabled or not.

 

[tiduscrying]

In the latest release of AuReiNand, the system settings will display SYS or EMU based on which one you are booted into. I am sure the code for Aurora's implementation of the loader will show how she did it!
