Ashbad, speak to me at some point about this if you'd be willing to help me organize them onto it. Ashbad, speak to me at some point about this if you'd be willing to help me organize them onto it. just PM some link to this wiki, and I can start adding my stuff to it.

(edit: the whole image is taken as opaque and masked, and then the entire thing is alpha blended at the same level, which is given as a paramter) but because you prompted, I just whipped together a new format (RGBAX 56553, where X, for those few who don't know, is unused by the routine and can be used for something entirely else if wanted -- in this case, it's only 3 bits large per pixel) that uses a new type color_t_rgbax, which is 24 bits large instead of the original 565 color_t which is 16 bits. *Now* there's something to add to SC2.5
typedef struct {
union {
unsigned int : 24;
struct {
unsigned int r : 5;
unsigned int g : 6;
unsigned int b : 5;
unsigned int a : 5;
unsigned int x : 3;
};
};
} color_t_rgbax;
void CopySpriteMasked5655(const void*datar, int x, int y, int width, int height, int maskcolor) {
color_t_rgbax*data = (color_t*) datar;
color_t* VRAM = (color_t*)0xA8000000;
VRAM += LCD_WIDTH_PX*y + x;
for(int j=y; j<y+height; j++) {

int alpha = *data & 0x0000F8;
*(VRAM) = (color_t)((((int)((*data>>8) & 0xf81f) * alpha + (int)(*VRAM & 0xf81f) * (32-alpha) + 0x8010) >> 5) & 0xf81f) |

For me, decompressing is about 0.5 sec. for the 40320 image.

It fit into my program really well and I barely had to change anything: https://img.ourl.ca/rfg/mandelbrot-kerm-color.png
