Using cheats for practice:
Use the 3 saved files as follows. Turn ON the "God mode" cheat on the first file. 
Enable the "1000 Gold and Souls" code on the second file, and no codes on the third 
file. You can use the first 2 files to learn how to play with the game, then 
actually do so with the third file.
