Homebrew Development

-exheader is only for CXI build.

 

Has anyone with Gateway or that leaked CFW managed to get APT_LaunchLibraryApplet to do anything aside from just freeze the 3DS? I used the example in libctru which tries to launch the circle pad pro calibration applet but it just freezes the entire console (does it matter that my system is on 4.3?). I also tried the camera, which freezes.

 

Well the example tries to launch applet 0x408, and 3dbrew has it listed as 0x208. (http://3dbrew.org/wiki/NS_and_APT_Services#Library_Applets) Don't know whether that's a mistake in 3dbrew or the example, but I'd try 0x208 and see what happens.

 

Noobish question:
Is it possible to write Launcher.dat executables in C or only ASM?

 

I'll try 0x208. Thanks. My main goal is to figure out how to pull up the software keyboard eventually; it'd be nice to know how. If I get it working, I'll share an example. I just wanted to use a "simpler" applet in the meantime, to figure out how to use APT_LLA properly.

 

In C only yes, LibCTRU's Hello World example does that, only ASM? I don't know, I think so something weird with the compiler though with .text and .data files..

 

Hm..I think I'll wait until my Gateway gets here before I mess with this further. This CFW is too unstable for any serious development..

 

Were can i found a sample for a Launcher.dat wrote in C?

 

Oh wait sorry, Launcher.dat .. I don't know, I thought you were referring to any homebrew project..

 

Check first post

 

Anyone ported zlib yet, or another unzip solution?

 

idk if it works: https://github.com/DownloadMii/DownloadMii/tree/master/libs

 

I dont see why zlib wouldn't work by simply compiling it with your project.
I know lz77 works and there might even be some Service API calls for those on the 3ds already.

 

zlip uses only I/O functions so doesn't need nothing to be ported to 3DS.

 

Yeah, however i cannot mange to get minizip to work correctly, will try lz77 .

 

Out of curiosity, has anyone tried to figure out how Smash Bros or Monster Hunter asks for extra memory from the system?

 

I suppose the MMU is asked for a bigger allocatable memory (through SVC , MCR / MRC co - ops) (for the kernel process)

On the NDS I use MCR/MRC for MPU locking-down pages

DTCM data region lock enable

detect DTCM base + 0x3ff8 (for BIOS flags that raise interrupts through swi code)

 

Guys do you know which font is the one used by Bootrom when showing errorcode?

 

Standard C I/O library (fopen, fclose...) what format of path does accept? ("sdmc:/Myfile.txt" or just "/MyFile.txt" ?)

 

Nothing?
