Ok thanks. Should add a name in the credits for the help?
Eww, why some functions asks char, and elses asks shorts?

CopySprite, and all thats use the Sprite Coder tool

So, We must now convert theses functions, and change the sprites, right?

I saw that, and I made that on alpha_clip...
So... Maybe tell with cemetech to change Source Coder?

Test with copysprite

void CopySprite(short* data, int x, int y, int width, int height) {
   short* VRAM = (short*)0xA8000000;
   VRAM += (LCD_WIDTH_PX*y + x);  // what should I do?
   for(int j=y; j<y+height; j++) {
      memcpy(VRAM,data,width); // and here?
      VRAM += LCD_WIDTH_PX;
      data += width;
   }
}Is is right? I can't now test

Do you mean to say zoomed as in a scaled sprite? That is doable but I think you would want to change that function to say Z_sprite(short * spr, int x, int y, int width, int height, float factor)
It is better to use a float there because the factor is often not an integer value especially if you want to shrink a sprite.

The size of float based routines is really quite negligible and they don't use any extra ram because the entire executable is stored in flash. You could use a fixed point float in this situation but I would advise against them in this situation as the best way to write them out would be to use pre-defined macros such as TWO_POINT_FIVE which would be 0x00028000 in a 32 bit fixed point notation. The other alternative here is to specify when calling the function what size you would like to scale it to instead of providing a scale factor. Perhaps in this situation 2 different functions ought to be developed. One for rather straightforward scales that can be easily implemented such as x.5, x2, x4 and so on. This would be called as 2 raised to the x power. For example passing 0 as the scale will result in a sprite with no change in size while 1 will be x2, 2 as x4, 3 as x8, and so on. That would also mean that -1 would be .5, -2 as .25 and so on. The second routine would require much more overhead and be called with either a float factor or specify the new image size. If this sounds good I can start work on the first routine and have that out in not too long.

Set colors to a short? Useful for paint-like things (that i want to make...)
short setColors(unsigned char red, unsigned char green, unsigned char blue)
return ((red & 0x1F) << 11 ) | ((green & 0x3F) << 5 ) | ((blue & 0x1F));
ANyone to optimize this?

Damn, double post... What would i do?

Yeah! Forgotten that!
