1st step:
 ---------
 
 Find the earth800.bat OR earth640.bat in the earth 
 directory. It should look like this for the earth640.bat:
 
      if not exist vxdldr.exe goto DOS
      start /m vxdldr.exe
      :DOS
      eregcard.exe
      dos4gw game.exe x640
 
 Now add the following commands to the file (MS WW) 
 to make it look like this:
 
      if not exist vxdldr.exe goto DOS
      start /m vxdldr.exe
      :DOS
      eregcard.exe
      dos4gw game.exe x640 MS WW
 
 Do the same with the earth800.bat and the 
 first step is complete.
 
 2nd step:
 ---------
 During the game, hold down the SHIFT key 
 and type the following commands:
 
 rthcshe   = gives you 5000 cash every time you type it in
 rthshowmp = self-explanatory... shows the whole map
 
 Water Battle Defense: 
 ---------------------
 In case the water troops get too powerful,you should 
 build some WTP 100 air-cushion transporters and place 
 some SPIDER or SPIDER 2 units on them.
