This is a hint and a cheat. When the horse races come, if you want to make money, heres what you do. Bring your basket with you too! stand outside rose square and save just before you go in. find the winners of the races, turn your game boy off, and then go place bets on the ones you know will win. i did it 3 times, it works 2 out of 3 times so it might not work every time you try it.
