I need a faster way to do this....

Take a look at this extremely sloppy code and try to improve it plz. It draws a map from an array. The theme sets different tilesets, becuase the whole thing screws with a two digit number, so I have to use 0 through 9 and -1 through -9, but don't worry about that, I just don't want it to draw so slow. It's not bad until you try to juggle 3 map layers, and even one layer draws slowly, and you can see it drawing from left to right, I'm on a 500 MHz AMD K6-2 for crying out loud, and this is a 13h program! It's not the drawing functions, it's this sloppy map drawing function I made in like ten minutes.

int DrawMapLayer1(int mapnumber)
{
switch (mapnumber)
 {
 case 1:
 switch (mapone[0][0])
 {
 case 1:
 theme=1;
 break;
 case 2:
 theme=2;
 break;
 }
   maponeloop:
   if (down!=21)
   if (right!=12)
   switch (theme)
   {
   case 1:
   switch (mapone[right][down])
    {
     case 1:
     Draw_T_grass(drawpositiondown,drawpositionright,'n');
     right++;
     drawpositionright=drawpositionright+16;
     goto maponeloop;
     break;

     Draw_T_hole(drawpositiondown,drawpositionright,'n');
