Homebrew Homebrew Development

int time = (int)time(NULL);

I meant that I understood and didn't need anymore help, but thanks for the effort

Is there any way to get the current date ?
Can't seem to find a function that would give it

Also, is it normal that svcGetSystemTick() returns 0 ?

So today I "finished" a port to the DS of a program I wrote in my CS class - a craps simulator. I've made some adjustments to it, including adding a credits system and, today, a dice tossing mechanism. What I'd like to know is if it'd be "acceptable" to make a text-only homebrew and release it as a way for me to practice coding in C++ as I'm doing in class. Would anyone mind if I ported a simple text-based application that doesn't really do much?

btw, if you want to try the NDS version, you can get it here: https://dl.dropboxusercontent.com/u/34957059/craps-ds.nds It gives an idea of what the application will behave like, although it'll get adjusted to account for a 3DS screen width and whatnot.

That should run just fine on 3ds with very little change. I believe wintermute copied the console library straight from libnds, even leaving the rgb565 color in lol. (much to everyone's chagrin)

Did the community ever figure out how to enable the extra controls the N3DS provides, for CIA-based homebrew applications/games?

Yeah, the code is relatively simple. I'm just getting familiar with the concepts of C++ and working without intellisense and all the tools that I've come to use in VS and Netbeans, so perhaps I'll try making a 3DS version of it as well just to play around and get used to coding in different ways for different platforms.

Alright, to answer my own question, all we have to do is add ir:rst to our CIA RSF and it works, at least with Reinand..no clue about Gateway/the other CFWs.

Edit: Works fine in Gateway too. I guess it was a libctru or makerom problem back when we couldn't enable it..

Be aware that, from my experience, your CIA will not work on firmware versions before 8.0.0 or so, whenever ir:rst was added.

 

[daxtsu]

That's not really a big deal, can just have the makefile spit out a non-ir:rst CIA.

True. I suppose it really isn't as much of an issue now anyway, as unlike before when the 4.x CFW was somewhat common, just about every CIA user is either using a relatively high sysNAND version or the latest emuNAND.

I've got some trouble with displaying an image, and i can't directly find an example for this.
someone got an easy example which loads and displays an image from the SD?

Thanks

I made one in LUA, but I am assuming you are using C or C++

I would prefer c
EDIT: i remember an example in a wordpress website.
But i can't find it anymore

Well, if you don't get anything better, feel free to look at my homebrew that displays an image on the top screen and an image on the bottom screen.[RELEASE] Capture Card Alignment Tool It isn't in C, but like I said, if you don't get anything better.

 

[Tjessx]

I think i will just do it like it is done here:
https://github.com/xerpi/sf2dlib/blob/master/sample/source/dice_img.c
converting the image into a c array, and using that to draw it.
If necessary i'll change it later

Or you can use something simple to load JPEG's or PNGs. It really isn't hard to blit images to the framebuffer, once you sort things out.

Could you give us the source of that?

You can find CPU rendering library i wrote for lpp-3ds here: https://github.com/Rinnegatamante/lpp-3ds/blob/master/source/include/graphics/Graphics.cpp
If you want to use GPU, you can see sf2dlib samples.

 

[mudlord]

The image loader used was stb_image. Custom routines to blit to framebuffer and rotate the image was used to take account of the 3DS's rendering orientation. The rotation code could be optimized in ARM ASM I guess.
