EDIT: Maybe you should initialize SDL as 8 bpp? nSDL handles 8 bpp on CX, and as you're only dealing with 8 bpp stuff it would maybe be easier to concentrate only on one bit depth?
Yeah, I can try that, but I don't know how to

Yeah, but what's the code you're using ? You told me to use SDL_DisplayFormat, I did so.

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 ?
Also,Yeah, that would be a perfect candidate for tilemapping.
^ I don't understand that (sorry, French inside)
The picture would be good for tilemapping because there are a lot of repeated patterns in there.
Oh okay  And shaders aren't part of the original SDL, but why not make ones for nSDL ? We're not restricted to functionalities already existing in the original lib (see nSDL_LoadImage and others).

I attached the image that caused problems.
Also I think that some kind of shaders would be cool, like colour modifying or others.

I wondered, are you using a getCSC hook or a getKey hook ? In any case, how are you testing the ON key ?

Yeah, I got that several times too o_O

To render the scene, my Mode7 engine does setPixel(screen,x,y, getPixel(bitmap, textureX % IMG_W, textureY % IMG_H));... Plus some more calculations 14325 times. I don't think that testing 44*16 additional pixels will change anything to the speed  (moreover, the Mode7 engine uses floats - I'll optimise it later, and the detection engine will be restricted to ints).

Yeah, I think that's the best way to do this because walls can be one or a half of a tile, when the finish line, dashes, jumps and power regenerators are always a full single tile.

I'll just go with pixel testing, I want to have a respectable accurance with collisions.

In fact I'll go with tilemaps. The whole image can't even be entirely loaded, it's 800K in gif format but 42MB in raw format  So I'll recode the display engine. Updates coming soon

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

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 ?

Not that I can't do that, but I also want users to be able to create, load and play with their own maps, so hard-coding maps isn't a solution. But for the draw-to-a-buffer thing, I could do that but that takes even more space than a single image map (tilemap + tiles + buffer, instead of only map).

I can't blit a bunch of aligned images, I need to transform and blit separately each pixel of them And precisely, for generating each pixel of the large image (pixels which you will, indeed, later transform and draw separately), you could use tilemap definitions + tile images
Yeah I know that, but now that I think of it, using tiles is slower than parsing a whole map, because in addition of the initial operations that applies to a large map you'll have to find, load and apply calculations to pixels of different tiles (things that you don't have to do with a single image). Of course it saves size, but make the program slower. I think I'm better with a single image per map (that doesn't mean I can't change my mind tho, if I optimize my program to go fast enough maybe I'll have both speed and lightness).
