The main problem is that I don't know what u8* screen refers to. The one I used was referring to GFX_TOP.

EDIT: Nevermind it works fine. Just colors are messed up.

Sorry, you can replace that variable since you used this:
u8* fb = gfxGetFramebuffer(screen, GFX_LEFT, NULL, NULL);
instead of screen use fb in the functions

 

[UltiNaruto]

Yeah I noticed this

--------------------- MERGED ---------------------------

here's the original background :

400x240x32
and the blocks in are 20x20x32

--------------------- MERGED ---------------------------

I fixed background but blocks are still not good and the blocks renders down when I want to render a block out of screen.

--------------------- MERGED ---------------------------

I can release my game as of now but it has few graphics glitches

EDIT:
I'm a complete idiot ...

Is there a way to set a video mode with pixels memory location following the X axis instead of the Y axis?

I remember to read something about this on 3dbrew long time ago, but can't find it anymore. Maybe I dreamed about it ...

 

[UltiNaruto]

Well the x and y axis aren't a problem anymore. And same for the PM I sent you.

Sorry, I missed your PM. Reading the forum from my smatphone sometime happens that notification are cleaned without noticing them.

For the x and y swapping, you mean using sf2dlib? I can't use it, I need to write directly on the fb two pixels at a time (using a bidimensional lookup color table) to boost a little the z26 emulator.

 

[UltiNaruto]

Well using the 2 pixels trick should be better. I'm doing this with 32 bits png. Though I don't use the alpha channel.

 

[nop90]

But the enulator produces two consecutive pixels on the x axis and if I have to split them i lose speed

Well as I said I'll stick with the current drawImage function. But is it possible to get profile name?
I wanna use it for a high score table.

It's not supported in ctrulib, but if you know the memory location you could possibly use it.

 

[UltiNaruto]

Well I'll have to debug it then not sure of how I'll do though. Debugging ARM processor without ARM assembly knowledge is pure suicide xD
I only know x86 assembly... and a bit of x64

the save file described in this webpage contains the username.
You could possibly extract it from here, not sure though:

Thanks for the link I'll try this later I'm updating homebrews on my 3DS.

EDIT: I saw something like that in cfgu.h

EDIT2: This?

Result CFGU_GetConfigInfoBlk2(u32 size, u32 blkID, u8* outData);

EDIT3: That's the only example I could find.
https://github.com/smealum/ctrulib/blob/master/examples/get_system_language/source/main.c

EDIT4: Here's the function for those who needs this.

char * getProfileName()
{
    Result res;
    u8 * tempProfileName = (u8*)malloc(0x16);
    char * profileName = (char*)malloc(0x16/2);
    int i;
    for(i=0;i<(0x16/2);i++)
        profileName[i] = 0;
    res = CFGU_GetConfigInfoBlk2(0x1C, 0xA0000, tempProfileName);
    for(i=0;i<(0x16/2);i++)
    {
        profileName[i] = (char)((u16*)tempProfileName)[i];
    }
    return profileName;
}

EDIT5 :

Returns the length of the profile name and takes the profile name as out parameter

#include <3ds/types.h>

int getProfileName(char * profileName)
{
    Result res;
    u8 tempProfileName[0x16];
    int i;
    
    for(i=0;i<(0x16/2);i++)
        profileName[i] = 0;
    res = CFGU_GetConfigInfoBlk2(0x1C, 0xA0000, tempProfileName);
    if(res != 0)
        return -1;
    for(i=0;i<(0x16/2);i++)
        profileName[i] = (char)(tempProfileName[2*i] | tempProfileName[2*i+1] << 8);
    return strlen(profileName);
}

Is there any way to get the current date ?
Can't seem to find a function that would give it

Also, is it normal that svcGetSystemTick() returns 0 ?

 

[UltiNaruto]

This should do the trick : http://www.cplusplus.com/reference/ctime/ctime/

[UltiNaruto]

ah didn't know this

 

[Tjessx]

time(NULL) gives the current timestamp.
You could write a function yourself to calculate the date

 

[Stracker]

Alright, perfect, just needed a way to get an integer timestamp, thank you very much !

int time = (int)time(NULL);
or
int time = (int)osGetTime() / 1000;
