I haven't read the whole thread, that was just a question.
The cheat is usable in single player only, but it can be stull unfair (ah, no, this isn't the right word - you're playing alone, so there're no fair/unfair things). BTW you're all alone, and you can do it for fun, but I hate cheats, and I like preventing players from using them, and things like that - for example the save blocker snippet. It's my (bad/good) habbit, someone jusges me while others thinks the same. It depends on Raven0.
