Well it depends on your motivation. But if you decode png through code, you can then easily modify your image on your needs in case it's not perfect on first try.

Anyone mind shining some light onto the situation? :/

Variable declaration in a for statement is allowed onlt in C99 mode or in C++.
Also it seems you're re-declaring the same variable.

alright, nevermind the png-decoder example, I'm having trouble with the output .bin files. :/

Whenever I apply them to an object, they just seem to display junk as the texture.

Does the image need to have a specific size?

 

[UltiNaruto]

if you want your image to output as .bin offline you should rather look at this then :
devKitPro\examples\3ds\graphics\bitmap\24bit-color

gpusprites example is tiled into 1/4th of the image and it's loading a .png on runtime.

I still don't understand... I don't seem to get a .bin file when I build the 24bit-color example.

Ah indeed it's bgr. Sorry about that.

Is there some problem in the logic of this piece of code? I tried it on Citra and seems to work quite good most of the time (i want to make it work always) but on Windows i always get a stackdump trace:

float* vert_args = (float*)res; // Hacky way to iterate in vertex struct     
printf("writing vertex at ptr 0x%X\n",vert_args);
fflush(stdout);
while (init_val < end_vert){
       if (end_val > end_vert) end_val = end_vert;
       strncpy(float_val, init_val, end_val - init_val);
       float_val[end_val - init_val] = 0;
       printf("inserting vert_val (idx %i): %s...",idx,float_val);
       fflush(stdout);
       vert_args[idx] = atof(float_val);
       printf("done\n");
       idx++;
       init_val = end_val + 1;
       while (init_val[0] == ' ') init_val++;
       end_val = strstr(init_val," ");
}

In runtime i get this output before the crash:

searching for next vertex.. (vl: 0x53990 / vert : 0xA333838)
writing vertex at ptr 0xA333838
inserting vert_val (idx 3): 0.655716...

what about if(end_val >= end_vert) . I can see an exception raised due to stack overflow edit: or atof() failed to convert the value to float due to value not being numeric (ASCII does not represent a number)

I found the problem, it was caused by res pointing to an unallocated memory region in certain circumstances

Is the Circle Pad Pro (for o3DS) compatible with homebrew ? At least with ctrulib ?

Last I remember reading, no it's not yet.

 

[spinal_cord]

Quick question, I tried building my emulator (breadbox) as a .cia, it installed fine, but when I hit the home button it freezes. I assume there's some code for detecting the home button? other apps such as blargsnes and gameyob don't have this issue.

Any help?

 

[~Poke~]

Hey, I have a few questions here but they're all relatively simple (or not, but, broad so probably have been considered before?)
Is there any way to create a background thread (always running, while playing games and etc.) outside of building it into a CFW, or doing a ninjhax2.5 style takeover of the whole system?
I suspect that the Home Menu applets work like this (Miiverse, Friend list, Browser)... do they?
If so, is it possible to replace them with a Homebrew .cia? I understand it would need to be compiled differently since they're a different type of app, do we have the capabilities to do this?

Does someone knows why sf2dlib seems to be unusable after citro3D initialization?

It looks like whenever i try to load certain textures to use them on a model i get these two errors on Citra:

unknown GetPointer @ 0x00000000
DebugUtils::LookupTexture Unknown texture format: f

The same code works if i load the texture BEFORE initializing citro3D. :/

 

[francovp]

It's browserhax working? Can anyone test it?
