|Infinite MVP Points|
Reach a desired level of MVP points to spend on a player, stadium, or throwback jersey. Use them to unlock a bonus, then save your roster. Do not save your profile. Instead, reload your profile. Your MVP points will be at their pre-purchase amount. Use them to continue buying as many other bonuses as desired.
Start a dynasty with a team that can make the playoffs (for example, the Yankees). Simulate all the way to the last series, then save the dynasty. Then, simulate to the playoffs then advance to the playoffs. Save your profile (not dynasty). Exit the dynasty and you should have between 5,000 to 10,000 MVP points. Do the same thing as many times as desired to unlock everything.
Select dynasty mode and choose the Yankees. Turn off injuries, trades, rain outs, and budget. Set the difficulty on MVP. Simulate to the last game of each month. On that game, choose to simulate it (not quick sim; choose "Play" then "Sim"). Stop the simulation at the top of the ninth inning and choose to manage the remainder of the game. Do this for every month for the rest of the season. When the season ends, and you see "Advance To Playoffs", save the dynasty. Then, choose "Advance To Playoffs". Each time it will show your points earned.(about 13,000 to 17,000). Do not save after this. Exit dynasty mode, then keep re-entering and choosing "Advance To Playoffs". Each time you do this, you will get that same MVP point amount put into your profile.
Start a franchise then simulate the whole season. Pick a good team for more points (Giants, Yankees, Marlins, etc.). You should get about 7,000 or 8,000 points, and more if you make the playoffs.
First, start a dynasty and choose any team. Turn off all the trade rules and the budget. Then, go to trade players and trade away all the bad players for the best players for all three of your teams so they will all win. Do not forget to get the good players out of the free agents. Sim all the way to the end of the season. At the end you should have about 13,000 to 15,000 points. Then, continue through the playoffs. If your teams win every series, you should get about 900 more points. Continue to do this as many times as desired, and you should get about the same amount every time.
Enter a Home Run Showdown or a Pitcher Showdown. Select the opponent that you are supposed to defeat for points, and set their difficulty on MVP. As soon as the game loads, go into "Game Options" and switch the difficulty to any desired setting. As soon as you defeat the player, you will receive 200 MVP points (which is how many you normally get for playing under the MVP difficulty level). This also works for your dynasty as you go game by game.
