Cheats for All-Star Baseball 2003 (GAMECUBE)

Cheat menu
At the controller select screen, press L to use the cheats you've unlocked.

Better pitching
The best pitchers have a pitch called a "Slurve" (for example, Mark Burhele of the Chicago White Sox). Also try the "Dominate Curve" with Pedro.

Restore pitcher's energy
In season, franchise or expansion mod, go to the DL, and put any pitcher on the15 day DL. Then immediately take him back into your lineup. He will have recovered all his energy.

Better franchise or expansion mode teams
Use trades to get rid of your older less talented players for slightly better players. Even if the CPU rejects your trade, keep trying repeatedly and it is usually eventually accepted. However, make the trade reasonable, such as B- for a B or B+. If the player you really want just does not seem to want to join your team, try trading for another player who is slightly better, then return to that player you want and try again. Do this every season to keep good young players.

Easy cards
Use the following trick to unlock all the cards in one or two games. Once you unlock the Cooperstown Legends and the Pixels, play as the Legends. You will find that within the fifth or sixth inning, every hit equals ten points and possibly more. Constantly hit homeruns and strike out the batters and you should have forty to fifty packs to open after the game. This is the easiest way to complete your card collection and unlock the cheats.
