MLB 2006
Better pitcher management
If you are a starting pitcher and do not make the rotation and are a reliever, do not just simulate over the games. When you are on the scheduled game square, press X then go to simulate to next appearance. By doing this, you can control your player and not just let him go. If you just let him go, he will do no good.
Fart mode
Pause game play, then press Up, Up, Down, Down, Left, Right, Left, Right.
Franchise mode options
Select from the options: 'Game Modes', then 'Franchise'. Select 'Business', and then choose 'Stadium'. You are now able to create your ticket price, seats, and other things. You are also able to choose 'Marketing' at the 'Business' menu and go to 'Promotions'. From that location you can make bobble heads, bat nights, ball nights, and television settings in 'TV'.
Get old timers easier
Go to season mode. Go to the playing schedule and it will have a list. Choose "Simulate Season". When this is done, you will have points to buy the old timers in profile mode.
Maximum speed in career mode
Speed is the most important ability to have in the game. To make the fastest player in the game, make him 6'10". This is the tallest you can make any player. The weight really does not matter as much, however make your created player at least 250 with a buff muscle tone setting.
