If you would like to use these cheats then you sadly have to
 use the DOS version but that doesn't really matter.  To
 activate the cheats you must go to the single player selection
 screen or network player selection screen and type the desired
 cheat followed by pressing return, and you must make sure that
 there are no spaces and that you can't see what you are typing.
 You will hear a beep if the cheats are entered successfully.
 Then once you enter the game press C and a + sign should appear
 beside the date, that tell you that the cheats are acitvated.

 If you are getting too many black marks from the council, get a level
 two house, and make the tenants 'the punks.' After a while they should
 start to complain about a hedge and will give you black marks if you
 do not drastically decrease their rent.
 Drastically decrease their rent, and you will receive some white marks.
 Then put it up again and repeat this until you have no black marks
 left. Then either replace them, agree to their demands or make them
 have children. P.S. if you continue to do this, you will receive many
 white marks which can be exchanged for cash. (100 marks for 10,000.)
