Notes and Comments

• The compression is the same as that used in the Simcity 4 *.dat archives
  
  

• TO CALCULATE THE FILE SIZES
  

* If the powerValue=0, the file size is the value of compressedSpecifics

* If the compressedSpecifics is negative, do (((powerValue+1)*65536) + compressedSpecifics)

* If the compressedSpecifics is positive, do ((powerValue * 65536) + compressedSpecifics)

 if (compressedSpecifics < 0){
   fileSize = (65536 * (powerValue_l + 1)) + compressedSpecifics;
   }
 else {
   if (powerValue_l > 0){
    fileSize = (65536 * powerValue_l) + compressedSpecifics;
    }
   else {
    fileSize = compressedSpecifics;
    }
   }
