Instructions
Complete all the Tamer Rank tests. These can be accessed from the game's menu and will challenge your knowledge of Digimon and the strength of your Digimon. Upon completing the last test, you will unlock the Legendary Tamer Test, which will require you to connect to another player.
Connect to another player. You can do this by pressing the "A" button on "Connect Now" after clicking on the Legendary Tamer Test. To do this, you will need to connect your emulator to the Internet. Each emulator has a specific way of doing this, so you should consult the documentation that came with your emulator. Once an Internet connection has been established, the game will begin searching for another player. A battle with the player will be loaded when you connect.
Defeat the other player to gain the rank of Legendary Tamer. If you fail, you can try again by challenging another tamer, but you will have to wait a few hours before attempting the test again.
