Homebrew Development

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:

Code:

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 

 

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

 

then there's probably a fault in your rsf.

 

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.

 

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.

Code:

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();

 

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:

Code:

static inline void putPixel565(u8* dst, u8 x, u8 y, u16 v) //Put RGB565 pixels in a Bitmap-like formatted buffer
{
dst[(x+(47-y)*48)*3+0]=(v&0x1F)<<3;
dst[(x+(47-y)*48)*3+1]=((v>>5)&0x3F)<<2;
dst[(x+(47-y)*48)*3+2]=((v>>11)&0x1F)<<3;
}

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!

 

// Solved

 

That tripped me out.

 

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

 

No.

 

Can you elaborate how you accomplished the above?
