You have two possibilities to cheat with an hex editor:
 
 Skills / Money:
 Open SAVE with an hex editor and check out the 
 following offsets:
 
 for slot 1:  300
 for slot 2:  82C
 for slot 3:  D58
 for slot 4: 1284
 for slot 5: 17B0
 for slot 6: 1CDC
 
 Hier change everything to
 63 00 A0 00 00 00 A0 00 A0 00 A0 00 8D 10
 
 Now you have maxed out all figures but Fatigue, which 
 still is 0. 
 If you need it again later in the game this hexing 
 can be repeated later again.
 
 Percent:
 Open END with an hex editor and change the first 11 rows 
 completely to FF. 
 Now you can see all pics in the CG room and everything
