MLB 2006 - Platform: Playstation 1

Fart mode:
----------
Pause game play, then press Up(2), Down(2), 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.

More playing time in career mode:
---------------------------------
To make sure your player gets enough at-bats and playing time, make his 
fielding rating as high as possible. If your player is a bad fielder, he 
will get substituted for a defensive replacement quite frequently, 
especially if it is a close game in the later innings.

Raising Stats:
--------------
Change the game tuning options to subtract all advantages from the CPU 
and give all of the advantages to player one When you create a position 
player, move the speed all the way up. This will allow you to artificially 
pump your stats. Your stolen bases will come at inflated rates. Singles 
will be easily stretched into doubles, doubles to triples, and triples to 
inside the park homers. It will not be very difficult for you to quickly 
build up your player stats, as the better you are the quicker your experience 
points will rise. Become a first baseman in the Detroit Tigers organization. 
You will have a strong lineup in the minor and major leagues that will get on 
base ahead of you, and give you RBI opportunities. Becoming a first baseman 
also cuts your errors down, because you are not throwing the ball nearly as much.

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.
