As you can see from the code I've discovered 4 important things:

   1. Reading the memory in address [0x1005334] gives me the Width of the map.
   2. Reading the memory in address [0x1005338] gives me the Height of the map.
   3. Reading the memory in address [0x1005330] gives me the number of mines in the map.
   4. Given x,y that represents a cell in the map, in column x, row y, the address [0x1005340 + 32 * y + x] gives me the cell value.
