So, I just noticed that for some reason my ctrulib/include folder lacks the hbkb.h file, anyone knows if it got replaced or where can I get it?

*
*      HBKB (HomeBrewKeyBoard) General Information:
*
*      HBKB is intended to be a useful Keyboard for Homebrew
*      Applications.
*
*      Usage:
*
*        First of all, you need to include the HBKB Header in
*        your Project:
*        #include "hbkb.h"
*
*      Checking User Input and drawing the Keyboard:
*
*      Use HBKB_CallKeyboard(touchPosition); to call the Keyboard.
*      The Keyboard Function is run with the current Touch
*      Position.
*      The Function will then Check the Current Touch Position and
*      write the Graphics for the Keyboard on the Bottom Screen
*      of the Nintendo 3DS.
*
*      NOTE THAT THE WHOLE BOTTOM SCREEN WILL BE OCCUPIED AND THAT
*      THIS LIBRARY DOES NOT CALL THE GFX FLUSH AND SWAP FUNKTIONS!
*
*      The HBKB_CallKeyboard Function will add Letters based on the
*      Touch Position to a String.
*
*      HBKB_CallKeyboard will after it was called return a Value (u8) to
*      inform about the current User actions.
*      1 = User pressed Enter
*      2 = User pressed any other Key except OK / Cancel
*      3 = User pressed Cancel
*      4 = User pressed no Key.
*
*      0 = Unknown (Something went wrong)
*
*      Also, the way this works is that it checks for Input first,
*      then draws the Keyboard. This is due to the drawing of the
*      Graphic for the selected Key(s).
*
*      Requesting User Input:
*
*      HBKB_CheckKeyboardInput() returns a std::string with the Input
*      the User made during the time the Keyboard was called.
*      This string is => NOT <= reset after HBKB_CallKeyboard() returned it's
*      u8 Value.
*
*      NOTE THAT THIS STRING IS NOT DRAWN BY HBKB! YOU NEED TO CHECK THIS
*      STRING AND DRAW IT YOURSELF!
*
*      Reset User Input:
*
*      You can reset the Keyboard with HBKB_Clean().
*

Is there a way to do a kind of reverse newline with the console, to force the contents downward? I understand I can shift the contents of the console upward by one row by positioning the cursor on the last row, and forcing a new line, but what I'd like to do is have it go the other way, as I'd use that and the previously mentioned as a means for scrolling through a list of items I print to the console. Rewriting all the items on the console causes it to sorta blink, but if I could just shift the console output by one row in either direction and just print the new item, it would be nice.

nvm. I was doing printing to both screens, and set up both so I could switch between them. Except when switching to the window with my list, I saw I wasn't selecting it, but initing it again, which caused the blinking.

Can anyone tell me what went wrong here?

NS_LaunchTitle V.S. APT_DoAppJump. What's the difference between them exactly?

NS_LaunchTitle V.S. APT_DoAppJump. What's the difference between them exactly?

LaunchTitle reboot the system i think (it should call NS_RebootToTitle), DoAppJump not.

/**

 */
Result NS_LaunchTitle(u64 titleid, u32 launch_flags, u32 *procid);

/**

 */
Result NS_RebootToTitle(u8 mediatype, u64 titleid);

I'll have a little experiment with it and see if I can do something with it.

the linker couldnt find the main (your app) user entrypoint . did you install devkitpro correctly? For example missing $(DEVKITARM) symbol can cause your code to not compile (and then some script with hardcoded path to linker would not find your compiled objects)

or you are trying to compile something that has not a main method in that folder, thus you need to make the whole parent folder first

could be anything

hmmm, just restored from an older version (it's the camera example program) and it works, maybe some sort of change between older devkitarm and the latest (which I assume then examples are updated when needed).

I'll just leave it at that.

Out of curiosity, are there any simple [open source] tile based games around, I know the 3DS doesn't have a native tile engine like the DS/SNES/NES/GBA/Gameboy did, but I assume someone have already had a go at a tile based background? I don't really want to reinvent the wheel if I don't have to.

You can give a look to RPG Maker 3DS i was creating but it's wrote using lpp-3ds.

Getting a pretty strange error in linking phase, does someone know how to solve?

c:/devkitpro/devkitarm/bin/../lib/gcc/arm-none-eabi/4.9.2/../../../../arm-none-eabi/lib/3dsx_crt0.o: In function `ClrLoop':

make[1]: *** [/c/Users/Alessio/Desktop/Repositories/lpp-3ds/lpp-3ds.elf] Error 1
make: *** [build] Error 2

This is the ClrLoop code:

ClrLoop:
   stmia r0!, {r2}
   subs  r1, r1, #4
   bne  ClrLoop

   bx lr

I suspect the ClrLoop is not the real issue. What is your signature for main?

Looks like i've deleted main file by mistake.
Anyway, after updating devkitArm, it looks like error handler is a bit messed up (it reports wrong functions (like the CrlLoop), for example:

luaSound.o: In function `$d':
c:/Users/Alessio/Desktop/Repositories/lpp-3ds/source/luaSound.cpp:1854: undefined reference to `ndspChn'

 

[TuxSH]

Nope, https://github.com/smealum/ctrulib/blob/master/libctru/source/ndsp/ndsp-channel.c#L40
"static"

 

[Rinnegatamante]

I know what the error refers to but luaSound simply doesn't have any function called $d: https://github.com/Rinnegatamante/lpp-3ds/blob/master/source/luaSound.cpp

 

[Spaqin]

Oh well, looks like I'm on the last steps before releasing my homebrew here.

The issue is now - how do I put banner sounds? With bannertool, given a wav exported from Audacity, all I get is chirps instead of the proper sound on the console.

i've been looking for a user friendly way to use images in homebrew.
I once heard of a way to compile the images within the 3DSX, but i can't find an example or anything written about.
Someone who could help me on the right track?
Basically i don't want the user to have to copy more then the .3dsx and .sdmh

A user friendly way is using romfs, because accessing it would the same as reading from the sdcard just with a different path. Here is the example: https://github.com/devkitPro/3ds-examples/tree/master/romfs
