Homebrew Homebrew Development

[AlbertoSONIC]

in C++ it's not actually possible to send arrays as arguments without losing a dimension so you'd actually need a 3D array with the first dimension zero and then you can pass it to get a 2D array, the way you're doing it now also sends the WHOLE array instead of a pointer to which is very inefficient

I got it to work using:

FUNCTION:
void guiBottomPaint(int color, int cTable[][SIZE1], int posxy[][SIZE2])
{
...
}

I basically had to write second dimension in the fuction itself and then i just had to pass the array's name:

guiBottomPaint(color, cTable, posxy);

Anyway i have another question. Is it possible to write a boolean variable? Something like

sprintf(buffer, "Value = %d", variable);

I'd say look here: http://www.cplusplus.com/reference/cstdio/printf/

If you really can't find it I'll tell you

Some news with the CIA file:
Now, i created a CIA which sounds good (it request only 3 MB for importing) but when i import it and try to launch it from emuNand, i don't get the normal 3DS loading screen (splashscreen with Nintendo 3DS and two rectangle on top-left and bottom-right of the screen) and after few seconds (1-2 seconds) i get the error screen which tell me to hold Power button to shut down console. How can i solve?

Have you stripped the elf? I can make CIAs properly with the following example:

arm-none-eabi-strip 3DNES.elf
makerom -f cia -o 3DNES.cia -elf 3DNES.elf -rsf build_cia.rsf -icon icon.icn -banner banner.bnr -exefslogo -target t

 

[Rinnegatamante]

Yes, i stripped the elf. 3DS build works fine but CIA build still crashes.

 

[Technicmaster0]

Yes, i stripped the elf. 3DS build works fine but CIA build still crashes.

then there's probably a fault in your rsf.

 

[Rinnegatamante]

I used the rsf i posted few posts ago. If you want try, i can give you my elf and try to import CIA that you generate.

Got a cool ray-tracer going.

3DS Banner Maker​

​

Create custom banner and icon files for your 3ds homebrews. Today I introduce you to an improved version of SnailFace's Banner Maker made by me! It has many usefull changes:​

Does this support making 3D/Animated banners? I think it's time homebrew gets the same fancy banners that retail games can have.

I just set up the devkit via the tutorial for Linux found here: http://3dbrew.org/wiki/Setting_up_Development_Environment

Everything went perfectly, and there was no errors at all. Yet, when I tried to compile the template source with the 'make' command, I kept getting the error below. It made a 'build' folder for which my output files should store, but no output files appear. This is beyond frustrating, and I hope one of you can help me.

No, actually it supports only PNG image so static banners (I think that if you try to use an APNG, it will also be converted as static).

Slushie3ds: Change gfxInit(); with gfxInitDefault();

 

[themperror]

When trying to build a .3ds for gateway use I get this: (It's the Hello-World project from CTRULib examples (in the graphics folder)

How can i decode BigIcon from SMDH?

According to info on 3dbrew ( http://3dbrew.org/wiki/SMDH ), i wrote this piece of code but icon is rendered corrupted:

static inline void putPixel565(u8* dst, u8 x, u8 y, u16 v) //Put RGB565 pixels in a Bitmap-like formatted buffer

Got a cool ray-tracer going.

Great!
I don't know if you saw my request in the homebrew request thread, but it's one of the thing I wanted

Raytracer, phong, etc. and also a simple radiosity renderer just for fun (monte carlo or other method).
I don't know if it's possible.

We'll see! This is actually my first time dealing with ray-tracer related stuff.
This was actually a port of an ascii-ray-tracer I made.

Once I have the time I'd definitely be up for making it much more advanced than what it is now!

That tripped me out.

Update to this since no one responded. I did it myself.

Could you make your mii have gold pants (special) with a Ninjhax program?

 

[Huntereb]

Could you make your mii have gold pants (special) with a Ninjhax program?

No.

 

[Slushie3DS]

No.

Can you elaborate how you accomplished the above?
