Source code

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;
	}
}

Inputs

x - X coordinate of the upper-left corner.
x - Y coordinate of the upper-left corner.
