I'm having problems trying to fill the screen (320x240) with boxes (GsBOXF).
Now if I use boxes of width and height 1 then I need 76800 boxes to fill the
screen - which I have tried and it hasn't worked probably because it
requires way to much memory. So I changed the box sizes to 4x4 meaning that
I would only need 4800 to fill the screen but this only works if I start
drawing the boxes at line 12?
Here is some example code:

// declaration

GsBOXF box[80][60];

// initialisation

for (y = 0; y < 60; y++)
  for (x = 0; x < 80; x++)
  {
      box[x][y].w = box[x][y].h = 4;    // size of 4x4
      box[x][y].x = x * 4;
      box[x][y].y = y * 4;
      box[x][y].r = box[x][y].g = box[x][y].b = 255;    // colour = white
  }

// drawing

for (y = 0; y < 240; y++)          // this needs to be "for (y = 12; < 240;
y++) " to work
  for (x = 0; x < 320; x++)
    GsSortBoxFill(&box[x][y], &WorldOT[acvtiveBuffer],0);

I've made sure my gpu packet area is big enough and even if I change the box
sizes to 8x8 (requiring even less boxes) I still can't fill the whole
screen. All I get is a flashing screen with 3/4 of the right side filled and
some corrupted boxes at the bottom.

If anyone can help or has any ideas then I would really appreciate it.

Thanks,

Rad.
