I've been trying to get into DS Homebrew recently using the DevKitPro and learning the ropes by tweaking some of the example files. In this case I was trying to tweak the 256*256 Bitmap example to display a different image and some text, here is my current code

#include <nds.h>
#include <stdio.h>

// This tells the program to include the image
#include "drunkenlogo.h"

int main(void){
    //Sets the correct modes
    videoSetMode(MODE_5_2D);
    vramSetBankA(VRAM_A_MAIN_BG_0x06000000);

    //Starts the console
    consoleDemoInit();

    //Prints text to the screen
    iprintf("256X256 BITMAP BACKGROUND TEST\n");
    iprintf("PRESS START TO END");

    //idk what this does
    int bg3 = bgInit(3, BgType_Bmp8, BgSize_B8_256x256, 0,0);

    //idk what this does either
    dmaCopy(drunkenlogoBitmap, bgGetGfxPtr(bg3), 256*256);
    dmaCopy(drunkenlogoPal, BG_PALETTE, 256*2);

    while(1) {
        swiWaitForVBlank();
        scanKeys();
        if (keysDown()&KEY_START) break;
    }

Whenever I try to make it it gives me this error

The image I'm trying to link is attached to this post. Can someone help solve my issue?
