Instructions
Insert your "Pokemon SoulSilver" cartridge into the slot on your Nintendo DS console.
Turn on your Nintendo DS and select "Pokemon SoulSilver." Press "A" or touch the title with your stylus.
Press "Start" or touch the screen to skip the intro cinematic and select the "Continue" option on the main menu to resume your game.
Touch the upper-right option on the lower screen's menu. There are two columns of options. Just to the right of the "Pokedex" button, you will see a card with your trainer name on it.
Look at the lower half of the upper screen. The upper screen displays the badges you've earned so far, with the top part showing badges from Johto and the bottom half showing Kanto badges.
