So recently I've been trying to make a little effect on a Casio Prizm and have finally managed to draw sprites to the screen (thanks to that new pre-compiled SDK, may I add!) though I've ran into another wall. I'm trying to fill the white background of my program with a blue color, but the pre-made function suggested by the wiki isn't working. Here is my code:

I've also tried using values that aren't LCD_WIDTH_/HEIGHT_PX and placing the line after using CopySprite but it still doesn't work. Any suggestions on what I'm doing wrong?

**Code:**```
#include <fxcg/display.h>
```

#include <fxcg/keyboard.h>

#include <math.h>

void CopySprite(const color_t* palette, int x, int y, int width, int height) {

color_t *VRAM = (color_t*)GetVRAMAddress();

VRAM += LCD_WIDTH_PX * y + x;

for (int j = y; j < y + height; j++) {

for (int i = x; i < x + height; i++) {

*(VRAM++) = *(palette++);

}

VRAM += LCD_WIDTH_PX - width;

}

}

void fillArea(unsigned x, unsigned y, unsigned w, unsigned h, unsigned short col) {

unsigned short*s = (unsigned short*)0xA8000000;

s += (y * 384) + x;

while (h--) {

unsigned w2 = w;

while (w2--)

*s++ = col;

s += 384 - w;

}

}

int main() {

const color_t sprite[2048] = {

CopySprite(sprite, 64, 64, 32, 32);

int key;

while (1) GetKey(&key);

return 0;

}

I've also tried using values that aren't LCD_WIDTH_/HEIGHT_PX and placing the line after using CopySprite but it still doesn't work. Any suggestions on what I'm doing wrong?
