See Championship Manager HEX-code, Hint here!

 This hack will allow the player to manage more than four
 clubs.  When he reaches the max number of managers allowed,
 you can edit the savegame file and then the number of
 managers to one, and then add another three managers. The
 player can repeat this exercise as many times as they want,
 this allowing the player to buy players from other clubs,
 and sell their own crap players at incredibly high prices
 and take as much money from other clubs as they want.

 First, load the game, choose the new game option.  Enter
 manager to start with, and enter your name.  Use manager
 one as your primary club. (it makes it alot easier).  Next,
 add another manager and choose a club.  You might like to
 buy their players or sell your own players to them at very
 high prices. Repeat the above step two more times to create
 managers three and four. Now resign the last three managers
 (manager 2, 3, and 4), but don't resign the primary manager.
 Save your game in slot one.  Quit, and back up the
 SVGAMEG1 file.
                                        
 Using a hex editor, edit the file SVGAMEG1, doing the
 following:

 Find Address: 43434
 change it from: 04 to: 01

 Save the changes, and reenter your savegame.  You'll be back
 to managing your current primary club, and have three spare
 managers available.

 Also, the best way to fix a game, is to click on a reserves
 team as opposition, and field as many reserves as possible.
 Also on the tactics team, put the goalie in a forward
 position.

A very useful tactic in Championship Manager to sell listed soccer players
that are watched by other teams that don't make offers is the following:
                                        
1. If you are playing with one team, you must insert a new player to have two
teams. (if your team isn't very good, you should insert a better team).
2. Now try to buy the player you want to sell with the new team, but make
a very very small offert: so if the team that are watching your player is
actually interested in him, it will try to buy the player immediatly:
exactly what do you want it to do.

More on: if you start the game with four teams (the yours plus the other
teams very powerful), you can buy the best players from the other teams and
so you will have a faboulous team! If a soccer player doesn't want to change
team, you must list him and then fine him one time a week: after two or three
weeks you will be able to buy the player without any problem.

The last tactic is for the cup matches in which the away goals are very
important: you should give very big bonuses for your player to make it score
and in the home matches you should use a difensive module (i.e. 5-4-1)
                                                   (M.B.)
