dot_blank -> thanks for answer. I'm trying. Do you think i can totally achieve in not using the prx stuff ?

moonlight -> very good news. thanks again for your work.

Thanks dot_blank to be more comprehensive. I really appreciate this. My question was about the possibility to make a library like libmad, which handles all needed for reading atrac3. The goal is to be able to link any homebrew to this library and use simple functions like libmad offers. I proposed a...

read the source people! you can easily integrate this into your own homebrew! ...its all there and there is already pspatrac3.h in pspsdk ! I've read the source, and my question shows it. This forum is about "Homebrew PS2 & PSP Development Discussions", so I suppose that I can ask que...

Sorry, to post again here, but I really think this libatrac3 can really be a must in homebrew devs.

Do someone currently work on the full pspsdk integration of this lib ?

I'm not sure whether i understand your answer. My question was about the the possibility to write a library like libmad, using the libatrac3 stuff, integrated to the pspsdk. When i look at the moonlight's sample 2, I see that it generates a prx module, which is not easy to implement in another proje...

Very interesting !! Do you think, it can be easy to use in the future ? For example, simple functions in the pspsdk like at3_init(), at3_play(char * music), at3_stop() ? I've tried your sample n°2, it works like a charm :) Just a little bug, when i browse to the music it has detected, some music are...

If you say this because of my post, please read again what I wrote :

I asked him to give his corrected code, so that it could be a sample.
I never asked him to use search function.

Please read !!!!!

I can be wrong but here is my thoughts : The only difference between a PAL and a NTSC game version is the graphic engine initialisation. Something like : Init_Graphic_Library(PAL) or Init_Graphic_Library(NTSC) These modes are "coded" in the bios of the console, so i think you can't change ...

Official manual :

Please post your corrected code, so that it could be a sample for people searching this functionality.

thanks

bulb -> ok, i have looked at libpng, and as you said, only two functions uses fread / fwrite : - pngwio.c : #if !defined(PNG_NO_STDIO) /* This is the function that does the actual writing of data. If you are not writing to a standard C stream, you should create a replacement write_da...

thanks for your answer jonny

the fact is libpng uses fread and fwrite, so we would load our png textures faster whether we rewrite libpng with write/read instead of fwrite/fread, or we find a solution to implement fwrite/fread with same efficiency

sorry, to post again here, but
i think the problem is not solved

bulb's tests revealed that sceIoWrite() gives better performance than using fwrite(). Is it normal ? Do someone know why or is it an unknown bug ?

where do you put that code ?

Hello,

Does the romdisk system is implemented in PSPSDK ?

A romdisk is a directory "linked" in the executable.

Thanks for your answer

Does anyone know how to easily use Ogg vorbis ? I know SDL_mixer handles it, but i'd like not to link SDL just for SDL_mixer, as I use PSPGL. An intermediate library, which helps using Ogg Vorbis could help using this format. The header could be : sndoggvorbis_init(); // to inialize vorbis sndoggvor...

Hello, i wonder whether the S3TC compressed textures are useful or not. From what i've understood : - DXT1 is for opaque textures, or transparency with just 1 bit (no level of transparency). It compresses 4x. - DXT3 and DXT5 are for transparent textures with different transparency levels. It compres...

Very good news ! Thanks for your work !

If i have understood your question, the answer is in the Makefile of the project.

Can you share your work to play ogg and wave files ?

did you use a toolchain ?

if so, just "make install"

I had exactly the same problem, but i didn't have answers here. I searched a lot, and I made a lot of tests to find that you have to define the PSP_MODULE_INFO("NAME", 0, 1, 1); at the beginning of your program (just after the declaration like #include or #define), and not to define the mo...

Well, i'm sorry, but i've just tested my app, and my psp reboots... So my new makefile, which allows me to compile fine, doesn't work as well as i thougt. All compile fine, but the execution failed... So, i start again with the old makefile, which just compiles fine my app before the need of using l...

well, i wrote my Makefile again, including the build.mak this time and it now compiles just fine. I don't have the old makefile, so i can't tell you my previous mistake. So it is resolved. If someone has the same problem, i advice him to test whether the screenshot program included in libpng compile...

Hello, i have a problem with libpng. when i compile my program, it says : /usr/local/pspdev/lib/gcc/psp/4.0.2/../../../../psp/lib/libpng.a(pngerror.o): da ns la fonction « png_warning »: pngerror.c:(.text+0x14c): référence indéfinie vers « _impure_ptr » pngerror.c:(.text+0x14c): relocalisation tronq...

thanks !

great to see that you try to improve the 2d code !

please don't hesitate to release some demo code.
perhaps a good thing is a "benchmark" code, in which we can see the different framerates with the different solutions to render 2d

Thanks for your work !

It will be nice if you edit the first post to put the corrected code.
So if someone else has the same problem, he could have a look at the bad code and its correction.

Thanks

thanks for your answer i like sdl, but i really think that it is a good idea to start a project using the more acceleration avalaible. i know the dreamcast scene, and the first sdl libs weren't hardware accelerated. chui recently released a sdl lib with hardware acceleration and it's very fast. I ho...
