Homebrew Homebrew Development

It's not so strange, the romfs service could use some nemory to handle reading calls amd some cache maybe.

The main point is that the game works with the emulator and with the 3dsx, so the romfs is called correctly.

With the Cia version there are two big differences: the program that packs the Cia file (makerom) and the enviroment where the exec runs (the 3ds normal enviroment instead of the homebrew launcher)

For the makerom I used my version that I know works fine.

For the enviroment I had a game running with no problem with the 3dsx and finishing the linear memory with the Cia version.

I don't have time to fully debug your code, I'm only giving you a hint.

You could try to change all the wav files with dummy file of only 1 sec of music (to save memory) and see if this changes something.

When I port games to 3ds I often have to lower the quality.of the sound files to make them load.
Good luck, debugging on the 3ds is always a pain.

I'll give it a try anyway. Thanks

I've posted a setup tutorial for Visual Studio 15, you can check it here. Maybe @aliak11 wants to link it in the OP.

Does anyone know how to build a simple location wrapper that works on 3ds?

Hi everybody. I've got a problem with this while loop that freeze the 3ds. I'm a bit tired and I'm 100% sure it's a really stupid fault but I don't see why it freeze...

void showRomPathMarquee(const int XposValue,int Ypos, std::string text) {
    std::string path = text;
   
    while(!(hidKeysDown() & KEY_UP)){
        while( clock() < (clock() + 100) ) continue;
        std::string scrolled,temp,temp2;
           
        temp = path.substr(1,(path.length()));
        temp2 = path.substr(0,1);
        path = temp + temp2;
        if(path.length() + 1 == ' '){
            sftd_draw_textf(font, XposValue, Ypos, SET_ALPHA(color_data->color, 255), 12, "%s %s", temp.c_str(), temp2.c_str());
        }else{
            sftd_draw_textf(font, XposValue, Ypos, SET_ALPHA(color_data->color, 255), 12, "%s", path.c_str());
        }
    }
}

Thanks everybody.

Thanks everybody.

You need to call hidScanInput() in the loop or the value returned by hidKeysDown() will never change.

Thanks, I forget to call hidScanInput() but it still freeze

        while( clock() < (clock() + 100) ) continue;

This is an infinite loop.

 

[umbjolt]

        while( clock() < (clock() + 100) ) continue;

This is an infinite loop.

Oh, I see... and how can I "stop" the main while? I want to print the string slower

double temp= clock();
while( clock() < (temp + 100) ) continue;

You can do something like this.But dDon't know if 100 is the riight value for your delay, and using it without the constant CLOCKS_PER_SEC is not very clean.

Thanks you. I changed double temp and temp + 100 to clk because temp was already declared but the method still freeze the 3ds.

 

[nop90]

Yes my mistake. Init clk outside the big loop and update it only after the if.

Anyway take this only as an exercise.

A clean way to do what you want isto sleep the execution for a given amount of time at every loop

Still no dice and I don't like to bother too much

Now I'm writng from a mobile and can't write the solution. Wait a couple of hours when I'll be at home please.

Can you help me guys?
I am using sfillib and I want to load image from sd card, here is code:

void Button::setTextureFromFilePng(){
    if(folderPath == NULL) return;
    sf2d_texture *temp = sfil_load_PNG_file("NCData/button.jpeg", SF2D_PLACE_RAM);
    if(temp != NULL)    buttonTexture = temp;
}

Here is pic with error that i get in citra.

Try changing this

    sf2d_texture *temp = sfil_load_PNG_file("NCData/button.jpeg", SF2D_PLACE_RAM);

to this:

    sf2d_texture *temp = sfil_load_JPEG_file("sdmc:/NCData/button.jpeg", SF2D_PLACE_RAM);

 

[ShinobuMeahera]

    sf2d_texture *temp = sfil_load_JPEG_file("NCData/button.jpeg", SF2D_PLACE_RAM);

to this:

    sf2d_texture *temp = sfil_load_JPEG_file("sdmc:/NCData/button.jpeg", SF2D_PLACE_RAM);

still the same.

I think you can ignore this error in citra. I have often such a error (more warning) in the emulator, bit I have no problems on the real hw.

The real problem is that in you code you're trying to open a jpeg with a PNG lib

When i lunch it on my 3ds and i load Graphic 10~15 times app just crash.
I want to make options where you can choose your own graphic and load it.
I know loading 10 times in row is stupid, but if it happens on citra and 3ds something is bad for sure.

No, its example function where i put path to img static. But in my app it looks like this.

sf2d_texture *temp = sfil_load_PNG_file(stringCat(folderPath, buttonFileName), SF2D_PLACE_RAM);

This sort of "busy" loop for timing is not really a good ideas as it prevents the CPU from doing other work while you delay. svcSleepThread is likely a better solution.
void svcSleepThread(s64 ns);
Where ns is the time to sleep in nanoseconds.
