You must have a profile made and
loaded. Do the training mode in the Coaches Corner.
Here, you earn "tokens", used a points. Whenever you
complete a certain play, you earn tokens. Do every
play that the game gives you. Try to do them
correctly so you can earn as many tokens a possible.
When you have completed each play, you can earn no
more tokens. Save your stats in the profile. Then, go
to the Madden Card section. In this section, make the
selection under the Challenge Status section (should
be in the middle). In here you can buy cards, just
like baseball trading cards. Cards are bought in
packs. Every card has a player (boosts stats by
certain percent), veteran player that you can sign to
your roster, Superbowl team (for example, the 1999
Rams), created team, new stadium, cheerleader cards,
and cheat cards. The cheat cards are cheats, just like
in Madden 2000 or 2001 (and some new cheats). You can
buy the cards with the tokens you have just earned.
Almost every card can normally only be used once.
Save the profile after you have all the cards you
want. You can activate all the cards you want, and
after the game, most of them will be gone. However
they will only remain gone if you save your profile
after the game. First, save the game, but do not save
the profile. Restart the game. Start the game
again and load the profile. Then, select Madden Cards:
Activate. If done correctly, all of your cards should
be back to the amount that they were. Do this after
every game and you should be able to use the cheats
indefinitely. Note: This was done in franchise mode.
