Ok, this is a great game.It got beautiful graphics, great sound, lots of replay value and yoshi.
When you first turn on your gba you can not the great intro (graphics etc), then when you play through the first level you can see the beautiful graphics seen in the snes game, the sound is also great.
As I said this gaem has lots of replay value because it got more than 40 levels to complete and it has minigames, plus the multiplayer mode where you can play with/against your friends in the classic mario that we love.
