Homebrew Save hiscore

Hello,

I wish I save the scores in a file on the SD card , as simply as possible ... the save file is created but it does 1ko and contains nothing ...

//A sauvergarder
bool niveau_unlocked[MAX_LVL];
bool niveau_solved[MAX_LVL];
u8 niveau_best[MAX_LVL];
//End save
 
void sauvegarder()
{
    fsInit();
 
    u32 bytesWrite;
    Handle fileHandle;
 
    char filename[15] = "/TILES_2DS.SAV";
 
    //setup SDMC archive
    FS_archive sdmcArchive = (FS_archive){ARCH_SDMC, (FS_path){PATH_EMPTY, 1, (u8*)""}};
 
    //create file path struct
    FS_path filePath = FS_makePath(PATH_CHAR, filename);
 
    //create file
    FSUSER_OpenFileDirectly(NULL, &fileHandle, sdmcArchive, filePath, FS_OPEN_READ|FS_OPEN_WRITE|FS_OPEN_CREATE, FS_ATTRIBUTE_NONE);
 
    //Write file
    for (i = 0; i < MAX_LVL; i++)
    {
        FSFILE_Write(fileHandle, &bytesWrite, 0x0, &niveau_unlocked[i], sizeof(niveau_unlocked[i]), FS_WRITE_FLUSH);
        FSFILE_Write(fileHandle, &bytesWrite, 0x0, &niveau_solved[i], sizeof(niveau_solved[i]), FS_WRITE_FLUSH);
        FSFILE_Write(fileHandle, &bytesWrite, 0x0, &niveau_best[i], sizeof(niveau_best[i]), FS_WRITE_FLUSH);
    }
 
    //Close file
    FSFILE_Close(fileHandle);
    svcCloseHandle(fileHandle);
}

You can look at the source of my Guess the Number. The only well-written part are the "files.h" and "files.c" files which contain exactly the methods you need. I think that you can write simply serveral saves by using one archive that contains serveral text files containing the scores.

You can also simply use standard functions like fopen, fwrite, and fclose (they're just simple wrappers in ctrulib as far as I know, but I don't see much of a need to use all of that messy 3DS init code when it's handled in the background for you), here's an example:

Ok thank you both , it works now ...

void sauvegarder()
{
    char filename[15] = "/TILES_2DS.sav";
 
    FILE *file = fopen(filename,"w+b");
 
    //Write file
    for (i = 0; i < MAX_LVL; i++)
    {
        fwrite(&niveau_unlocked[i], sizeof(niveau_unlocked[i]), 1, file);
        fwrite(&niveau_solved[i], sizeof(niveau_solved[i]), 1, file);
        fwrite(&niveau_best[i], sizeof(niveau_best[i]), 1, file);
    }
 
    //Close file
    fclose(file);
}
 
 
void charger()
{
    char filename[15] = "/TILES_2DS.sav";
    u8 erreur = 0;
 
    FILE* file = fopen(filename, "r+b");
 
    if (file != 0)
    {
        for (i = 0; i < MAX_LVL; i++)
        {
            fread(&niveau_unlocked[i], 1, sizeof(niveau_unlocked[i]), file);
            fread(&niveau_solved[i], 1, sizeof(niveau_solved[i]), file);
            fread(&niveau_best[i], 1, sizeof(niveau_best[i]), file);
        }
        fclose(file);
    }
    else
    {
        erreur = 1;
    }
 
    if (erreur == 1)
    {
        sauvegarder();
    }
}
