Hacking 3DS Homebrew Attempts

[Kirito-kun]

Guys! Look! I've managed to get Android 4.2.2 Jelly Bean to run on my 3DS!!! I'm liek 73h most Ub3r 1337 3DS h4x0r l0l0l0l0l!!! 1337 1337!!!

Here's something I vomited into MS-PAINT:

Just look at that amazing gfx! It pretty much sums up this thread....

This thread in a nutshell

 

[Xexyz]

well she did.

She included stdio.h library
she used printf, without stdio the small program could've failed.

last, C++ relies on objects, she used \n to skip lines, aand returned 0;

to keep the compiler happy you must return 0 always (end of function on the processor's thread, so program terminates)

Who's "she"?

 

[Coto]

Who's "she"?

you? or you're a he?

if so, i'm sorry.

 

[Xexyz]

you? or you're a he?

I'm a he. People make mistakes.

Never attempt to ascertain the gender of someone online. You will only fill your self with false hopes and disappointment.

mods should move this to EoF

This thread in a nutshell

Why do I have to be everyone else?

 

[Kirito-kun]

well you're wrong

If you compile that on a C++ environment, and you don't include

extern "C" {
#include "foo.h"
}

compiler takes for granted, that printf exists on the default system library header file. C++ re-using similar (by names) functions must be summoned, as shown above, so it runs directly from the C debugger (a.k.a C mode).

except, because it's now a C++ function, debugger appends garbage string data at the end of the binary blob at compile time. So the compiler is aware that function derives from C++.

printf's way to be called on C++

std::printf("I like std::!\n")

which is NOT how she used printf.

TL;DR version: she used C, not C++

Disregarding all the "theory", I just compiled the original code with a C++ compiler and it did indeed ran with no issues.

This proves that the original code *could* have been in C++.

My compiler is Bloodshed Dev-C++.

Why not just make a C/CPP/Programming thread?

My compiler is Bloodshed Dev-C++.

Naw, bro. GCC/G++/MinGW FTW

My compiler is Bloodshed Dev-C++.

Dev's okay for learning, but if you're going to be doing any serious programming (especially large projects), you should switch to Code::Blocks IDE with mingw32-g++ compiler.

IDK something went wrong with the image host/link? Disregard.

This thread never derailed. It was a train someone built off the rails and promptly driven off a cliff....

A train can't be driven without a rail.

I can do that in... 2 minutes ;D

Well, he tried to. No wait, he built the tracks facing a cliff, then it fell
