Mario coin mini-game:
To play the Mario coin mini-game, you will need at least one song file on the console that can be played in “Music”. While in the “Music channel” on the Nintendo DSi, start a song, then instantly pause it. Look at the bottom screen’s shoulder instruments. Scroll through until the “No sound” icon is displayed. Press Up repeatedly until the screen with Mario running appears. Press “Play”, and use L and R to make Mario jump. Note: The shoulder button sounds need to be set to “None” so that the audio does not become distorted.
Mario Bros. theme song:
To hear the Mario Bros. theme song, go to the “Sound Channel”, and tap “Record And Edit A Sound”. Do not touch anything on the DSi, and the theme song will begin to play after about one minute.
Parrot:
The parrot records sound at the starting screen. If you remain idle it will begin to repeat some sounds that the mic picks up.
Extra sound effects:
On the DSi Sound Channel, record a sound. Then, go to the box with four squares. On each of the squares there is either a parakeet, low harmony, trumpet, or electric fan. Click on one of them to alter the recorded sound according to the square you picked. If you click on one of the squares after it is already in use, it will change into a new sound. For example, if you are using the electric fan sound, it will change into a tunnel sound.
Photo Channel special effects:
Go to the DSi Photo Channel and use the distortion lens. Then hold one of the following directions (such as Up) and tap a location on the touch screen to create a special effect:
DIRECTION – SPECIAL EFFECT
Up – Make spot larger.
Down – Make spot smaller.
Left or Right – Swirl in either direction.
