Mastering the controls is your first step to becoming a Pokémon Master. The Nintendo DS offers a unique control scheme that utilizes both the D-Pad/Analog Stick and the touch screen. Here's a breakdown:

- D-Pad/Analog Stick: Moves your character around the map, navigates menus.
- A Button: Confirms selections, interacts with NPCs, examines objects.
- B Button: Cancels selections, runs (when held down after obtaining Running Shoes).
- X Button: Opens the main menu (Pokémon, Bag, Trainer Card, Save, Options, etc.).
- Y Button: Registers key items for quick access (after obtaining the Key Item registration feature).
- L/R Buttons: Scrolls through menu tabs, rotates Pokémon in the summary screen.
- Touch Screen: Can be used for menu navigation, selecting moves in battle, and interacting with certain features like the Pokétch.
Remember to experiment with both the physical buttons and the touch screen to find what feels most comfortable for you. Running is essential for traversing the vast Sinnoh region quickly, so hold down the B button once you acquire the Running Shoes early in the game.
