3ds exception crash when my .3dsx file is run through netloader

Super Mario 64 3DS Port Ultimate

Epic0522 · 2026-07-31T12:50:46+00:00

Hey everyone! I’ve been working on my own version of the Super Mario 64 3DS port for quite a while. What would Super Mario 64 look like if it actually treated the 3DS as a 3DS? This is Super Mario 64 3DS Port Ultimate. （The DS Bomb-omb battlefield minimap has been replaced in the newer version） Compared to the original SM64 porting project, there are more new features. Please use New 3DS to get the best performance. The complete source code, build instructions and development screenshots are available on GitHub: https://github.com/Epic0522/Super-Mario-64-3ds-port---Ultimate Credits This project builds on the work of the Super Mario 64 decompilation and porting communities, including: • n64decomp/sm64 • sm64-port/sm64-port • sm64-port/sm64_3ds • mkst/sm64-port and its earlier 3DS minimap work More detailed information and credits can be found in the GitHub repository. Thanks for checking it out!

Hi, I'm new to c++ as well as 3ds development, I set up a test Image to stay loaded on 3ds screen until forced exit. I get a 3ds exception. So my first question is why won't this run :

my .cpp

Code:

#include <assert.h>
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <iostream>
#include <3ds.h>
#include <citro3d.h>
#include <citro2d.h>
#include "main.hpp"
#include "intro.h"

C3D_RenderTarget* top, *bot;

static C2D_SpriteSheet introSheet;
static C2D_Image Img1;

int main(int argc, char **argv)
{
    gfxInitDefault();
    C3D_Init(C3D_DEFAULT_CMDBUF_SIZE);
    C2D_Init(C2D_DEFAULT_MAX_OBJECTS);
    C2D_Prepare();

    top = C2D_CreateScreenTarget(GFX_TOP, GFX_LEFT);
    bot = C2D_CreateScreenTarget(GFX_BOTTOM, GFX_LEFT);

    introSheet = C2D_SpriteSheetLoad("graphics:/gfx/intro.t3x");
    if (!introSheet) 
        svcBreak(USERBREAK_PANIC);
    u32 clrClear = C2D_Color32(0, 0, 0, 255);

    Img1 = GetImage(introSheet, 0);

    while (aptMainLoop())
    {
        hidScanInput();
        u32 kDown = hidKeysDown();

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

        C3D_FrameBegin(C3D_FRAME_SYNCDRAW);
        C2D_TargetClear(top, clrClear);
        C2D_SceneBegin(top);
        C2D_DrawImageAt(Img1, 20, 0, 0);
        C3D_FrameEnd(0);
    } 

    C2D_SpriteSheetFree(introSheet);

    C2D_Fini();
    C3D_Fini();
    gfxExit();

    return 0;
}

my .hpp

Code:

#include <iostream>
#include <3ds.h>
#include <citro3d.h>
#include <citro2d.h>

extern void DrawTexture(C2D_Image image, float x, float y, float rotation, C2D_ImageTint* tint, float scaleX, float scaleY);
extern void DrawTexture(C2D_Image image, float x, float y, float scaleX, float scaleY);
extern void DrawTexture(C2D_Image image, float x, float y);


#define TOP_SCREEN_WIDTH  400
#define BOTTOM_SCREEN_WIDTH  320
#define SCREEN_HEIGHT 240
#define GetImage C2D_SpriteSheetGetImage
#define GetSprite C2D_SpriteFromSheet
#define SetCentreSpr C2D_SpriteSetCenter
#define SetPosSpr C2D_SpriteSetPos

I would also like to know how to set up the gdp debugger for my 3ds(I'm working in VS Code)? I have the launch.json set up like this:

Code:

"configurations": 
    [ 
        { 
            "name": "Debug",
            "type": "gdb",
            "request": "attach",
            "gdbpath": "/opt/devkitPro/devkitARM/bin/arm-none-eabi-gdb",
            "executable": "./test.elf", 
            "target": "{3ds ip}:{3ds port}", 
            "cwd": "${workspaceRoot}",
            "remote": true, 
            "valuesFormatting": "parseText", 
        }
    ]

Is there a specific process I have to open while using the rosalina debugger? or am I not totally set up properly?
