How To Not Lose Money When You Lost To Someone In A ContestAdded 14 Dec 2012, ID #17747
If you're about to enter a contest with your own will, prepare your digimons properly and then go to DigiColiseum. When you're in there, save the game before you talk to Leomon for signing up. In this point don't save the game again. It costs a lot of money to sign up, so it is better for you to have more money than the price, just in case. After you fight the digimons and won your Tamer Rank will go up. Talk to BAN Leomon for a reward. If you lost the tournament then turn off the nintendo and you will start from the point before you sign up, and now you don't lose any money.
Enter the following codes without the quotes when talking to Valkyriemon inside the DigiColiseum to enable the corresponding cheat function. Valkyriemon will say 'It seems you know all the passwords' when you have entered ALL four of them.
