HexCheat:
 ---------
 To use: Hex-edit your saved game file. Be sure to 
 have a decimal-to-hexadecimal converter on hand. 
 If you do not know how to hex-edit files, it is 
 best not to even try.
             
 Offset - Size - Description
 
 94 - 2 - Current HP
 96 - 2 - Maximum HP
 98 - 2 - Current Mana
 9A - 2 - Maximum Mana
 9E and A2 - 4 each - Experience points (be sure to edit both 
 values so that they are the same!)
            
  Note: It is probably best to check how many experience points you 
  need for the next level, and enter that value (minus about 50), in 
  the 9E and A2 double-words. That way, you can also learn new spells 
  and the shops will have new stuff when you gain a new level.
 
 High Constitution: 
 ------------------
 To get High Constitution keep using a magic spell and keep using it 
 even though you are out of mana. don't be scared if your health goes 
 down. If you use the spell enough you hp will go back up and your 
 constitution will be maxed out
