It is not a cheat, it is a dizzy saved game. A saved game with 16 million of money written on it. The reason is: if you see on some screenshots the version says 0.9xx BETA. Some beta versions start with full access to the game and no limitations for doing everything (say, if there is a bug if you have a medicine and buy another, instead of replacing it it erases it.) I think that's why the easy 16 million form. In the final releases of the game, that were corrected to start, instead, of 16 million, start only with $300.

Now: the people like jonty is angry because its completely impossible to make so much money in little time (the necesary used to start a game, start with 16 million). If you have full access to the game even if it was beta, why to continue uploading the stats?

That is what's wrong. It is not fault of Arthur.
