Homebrew Homebrew app causes system restart

ThatBenderGuy · Oct 25, 2017

So I'm testing out a hello world example and compile it successfully to 3dsx and smdh. I launch homebrew launcher and select my app. Afterwords HBL locks up for a second then returns to the home menu followed by the prompt for a system restart. It's the standard hello world example given by devkitPro but here's the code for the app and the makefile

Running o3DSXL - 11.5 (Luma 8.1.1)

main.c

Code:

/*
    Hello World example made by Aurelio Mannara for ctrulib
    This code was modified for the last time on: 12/12/2014 21:00 UTC+1
*/

#include <3ds.h>
#include <stdio.h>

int main(int argc, char **argv)
{
    gfxInitDefault();

    //Initialize console on top screen. Using NULL as the second argument tells the console library to use the internal console structure as current one
    consoleInit(GFX_TOP, NULL);

    //Move the cursor to row 15 and column 19 and then prints "Hello World!"
    //To move the cursor you have to print "\x1b[r;cH", where r and c are respectively
    //the row and column where you want your cursor to move
    //The top screen has 30 rows and 50 columns
    //The bottom screen has 30 rows and 40 columns
    printf("\x1b[16;20HHello World!");

    printf("\x1b[30;16HPress Start to exit.");

    // Main loop
    while (aptMainLoop())
    {
        //Scan all the inputs. This should be done once for each frame
        hidScanInput();

        //hidKeysDown returns information about which buttons have been just pressed (and they weren't in the previous frame)
        u32 kDown = hidKeysDown();

        if (kDown & KEY_START) break; // break in order to return to hbmenu

        // Flush and swap framebuffers
        gfxFlushBuffers();
        gfxSwapBuffers();

        //Wait for VBlank
        gspWaitForVBlank();
    }

    gfxExit();
    return 0;
}

Oh, hey again.

Anyways, it seems to compile and run just fine for me:

It may be the version of the Homebrew Launcher you're using. Are you using this version of the Homebrew Launcher?

ThatBenderGuy · Oct 25, 2017

I'm using this version. I'm assuming I'm using the wrong version xD
Also hi again

EDIT:
Copying over the boot.3dsx you linked worked. I'm using the CIA version but didn't realize an updated boot.3dsx was needed. Thank you once again
