Homebrew Homebrew Development

[schuko1982]

Hello everyone, here a little tutorial to whom wanna begin with homebrew on 3DS

Before anything you will need these files:
DevKitARM : devkitpro.org
DevKitARM Add-on 3ds: http://mtheall.com/~fincs/3dsdkA/
3DSTemplate(with new ctrulib): http://filetrip.net/dl?rqkeqrIIns

After download all files:
1 - open the "dkA-3dsx-patch-12092014.zip" and copy the DevKitARM folder to DevKitPro/DevKitARM folder on your PC.
2 - extract 3dstemplate where you wanna, open the 3dstemplate folder and copy the "libctru" on C:/ or D:/ or where you wanna on your disk.
3 - Go to environment variables and at system variables, create a new with name: CTRULIB , value: D:\libctru (change to your libctru directory !).
4 - on 3dstemplate folder open the build.bat, if you did everything correct, it will generate three new files, ".elf", ".3dsx" and ".3ds", the .3ds is to Gateway users, .elf to alternative homebrew loaders and .3dsx to future Smea Homebrew Loader.

If you wanna edit the code, just go to source and edit the main.c, there is a little example on code, have fun

no valid link, someone can give it to me? DevKitARM Add-on 3ds: http://mtheall.com/~fincs/3dsdkA/

Thank!!

Thank!!

It’s included in devkitPro now.

Hi st4rk, and other people reading this.
Please note that the setup procedure is much easier now (devkitpro now includes mtheall's add-on and ctrulib natively)
But if you like writing tutorials, please join ours at https://github.com/xem/3DShomebrew

Hello everyone, i didn't knew about it, thank you for explaning =D

 

[williamcesar2]

Just passing here to say good luck to all your future homebrew people I have faith on 3ds homebrew scene (please ignore dirty pirates and butthurt people, they have no idea on how must of us are fine with usermode only )

ok hypocrite !

 

[VinsCool]

ok hypocrite !

Lol how would I pirate I haven't had a gateway.

Hey I have a quick question. I'm trying to write homebrew in c++, I was writing it in C but I'm not to comfortable with C, and I'm having trouble with my compiler and the function "u8* gfxGetFramebuffer(gfxScreen_t screen, gfx3dSide_t side, u16* width, u16* height);" . basically I want to draw to the bottom screen so I use screenBottom = gfxGetFramebuffer(GFX_BOTTOM, GFX_BOTTOM, NULL, NULL); and it doesn't work. can anyone point me in the right direction? please?

--edit

I'm sorry. I am a little tired basically what i want to do is clear the frame buffer not draw on the screen. using c++

gfxGetFramebuffer(GFX_BOTTOM, GFX_BOTTOM, NULL, NULL);
sb
gfxGetFramebuffer(GFX_BOTTOM, GFX_LEFT, NULL, NULL);
in 2d generally the left screen is the visible framebuffer. GFX_BOTTOM would effectively be referencing the right(as in GFX_RIGHT) framebuffer.

I find the dkA-3dsx-patch-12092014.zip

any help?

thank you

dkA-3dsx-patch is obsolete, new instruction install here =>https://github.com/xem/3DShomebrew

As you can convert .elf to .3dsx?

what are elf files? I never had to deal with them and managed to compile 3dsx files anyway.

when you compile the source using "make", creates three files .elf, .3dsx, and .sdmh. If I have not the source but if I have the file .elf I can use to convert .elf to .3dsx?

I got it. thanks in the function when you specify GFX_BOTTOM it does nothing with the 2nd part (GFX_LEFT). GFX_LEFT and GFX_RIGHT are only used when clear the top screen frame buff (left is 2d, right is 3d).the function works correctly though

Could you tell me how this funtions works?

drawCircleCircum(int cx, int cy, int x, int y, char r, char g, char b, u8* screen)

x and y are the circle's center position? And cx and cy are meant to do what exactly?

 

[minexew]

After about 5 hours of debugging I figured out that you have to call GPU_FinishDrawing before touching any depth buffer settings. Unless you want the GPU to lock up, that is.
Thanks, Nintendo!

I tried out the funtion. it seems cx and cy are the circles center position. but its not creating a circle outline at all. only 4s point around the specified center. btw what are you using to debug your app?

My 3DS I think i'll have to load a circle from an image instead of generating it...

so y is the radius and x is idk I put 3 and it gave me 6 pixels gonna try some other things. you could just drawFillCircle since you cant specify the thickness of the outline with the function you were trying to use.
Edit: Im gonna try and write a better function than this ^.^

I think this function may be drawing an ellipsis, so the X and Y would be the two radiuses.

yes it only draws a set amount of pixels not an actual circumference of a cirle.
