Nope, I removed SDL in the ds port to speed it up a couple of fps.

I compiled zlib 1.2.3 for DS.

edit: Link removed/obsolete. Best to use portlibs (http://devkitpro.org/wiki/portlibs).

I updated zlib to 1.2.3

Thanks I have updated my lib page with the new version.

Is there a tutorial somewhere as to how to get it working? I have been looking over the examples but they weren't very helpfull.

I would like to start with getting both screens to work, I'm already using devkitPro.

Thnx in advance,
Wasser

SDL 1.2.9 only supports a single screen.

edit: SDL 1.3 supports dual screen and touch input.

I'm having problems using SDL_image...
When trying to load an image with IMG_LoadTyped_RW or IMG_LoadXXX_RW it just crashes.. It only works when loading a bmp...
it looks that there is a problem when using libpng, libjpg or libz, but I can't find it...

I'm using devkitARM r23b

I never really used DS SDL_image. I don't think it was finished.

Well.. and what about SDL_mixer?? does it play anything? I've tried with a wav file but doesn't seems to work...
Edit: Debugging a bit I found that it freezes when calling SDL_BuildAudioCVT from Mix_LoadWAV_RW

did you build your project with the template? http://gpf.dcemu.co.uk/files/nds/SDL-1.2.9DS061507src.rar

ds SDL requires a custom arm7 core to have sound enabled.

also the latest ds SDL version is part of libsdl.org for the last couple releases, I need to update my site about that.

[hiperbou]

Yes, I'm using the template.
The makefile.ds isn't included on the official SDL sources, but I've compiled it and it seems that sound is working (I need to test it on the real hardware, because it sounds weird on the emus).
Thanks for your replies!

[hiperbou]

I just get weird sounds, using wavs or mod files... I have to initialize the librarie in some particular way?
I'm using with sound_freq=22050, or 11025 but got the same bad results...
Mix_OpenAudio (SOUND_FREQ,MIX_DEFAULT_FORMAT, 2,1024*SOUND_FREQ/22050)

EDIT:
Got it working with Mix_OpenAudio (11025, AUDIO_S8, 1,4096);
This means that no stereo panning can be used?

REEDIT:
I still got some "clicks" both on music and fx :(

It seems that if you play a sound, when it finishes playing, randomly keeps repeating noise or clicks for an undefined time. If you play a music on the background it does not happen.
It's annoying if you don't need a music to be played...
