Once plugged in you can turn on your game player and select to run the GBA cartridge if you’re using a DS. You’ll then have the option of choosing a thin dude or Mario to be your MP3 player mascot. Left and right on the D-Pad moves the character up and down the steps and selects the song associated with the current step. Press the A button to play and pause and even make your chosen character dance. And if you haven’t plugged in your headphones get ready for horrible music coming through your DS’ speakers.
How to make them dance.
Yeah so the DS’ speakers mangle any and all MP3’s. Plug your headphones into the DS’ headphone jack and it’s just as bad. Plug your headphones into the Nintendo MP3 Player headphone jack and it sounds perfect. Yep, even with all these quirks the sound quality is absolutely perfect and crystal clear. As your songs play you can tap the A button in different patterns to make your character do different dance moves and even bring out his or her friends on the vacant steps. It’s amusing for about 5 seconds.
