Is nDraw part of nSDL or is it a separate project?

There's no such thing as nDraw. Blitting (or "drawing" as I referred it to) is all part of standard SDL.

Great news! Hopefully this makes Matrefeytontias' F-Zero clone much smaller :P (currently, just one race track is 1 MB large)

So the picture on the first page no longer applies then.

Nope. Oh wow, that was nearly a year ago. ;D

Yay, awesome :D thanks a lot for it, I'll make a great use of it (especially with F-Zero yeah ;D )

ExtendeD I really would like you to fix the relocation issues, it's unbelievably horrible (but I suppose you know more than well enough the feeling I'm feeling right now, so no hurry).

Sorry about that. I really need tangrs to debug the issue with the bFLT loader and nSDL.

Here's nSDL drawing the OpenBSD fish loaded from a GIF file:

How did you make it to have the right colours from a gif file ? I'm loading a gif image from /documents/Examples/map.gif and it doesn't have the right colours at all ... Have I to save it as a gif with 16-bits colours ? If so, how can you do it with Gimp ?

Dunno, I just saved the file as a GIF on Paint. Can you post the file here?
EDIT: Try if passing the surface through SDL_DisplayFormat() and see if it helps. BTW, for a speed boost you should always pass your files' surfaces through that function, it avoids SDL having to convert to the display format on the fly.

Ew, Out of Memory D: it's true that uncompressed, my gif file is 42 MB ... I'll just go with tilemapping.

Did you fix the color issue or not? Could you attach the file that caused problems here?

I attached the image that caused problems.

Also I think that some kind of shaders would be cool, like colour modifying or others.

Yeah, that would be a perfect candidate for tilemapping. As for shaders, wouldn't you just write those yourself in C?

Of course I could, as for every SDL command ._. but since it can be optimized to work together with SDL, why do not ask hoffa ?

The picture would be good for tilemapping because there are a lot of repeated patterns in there.

I don't think shaders have ever been a part of pure SDL.
