i think 2 paper luigi and luigi`s mansion this is for ds only
Afraid not. If you're looking to play with both Luigi and Mario in a RPG style game, try the "Mario & Luigi" series spanned across the GBA and DS portable gaming systems.
there is no such thing as baby luigi but there is baby luigi in Mario kart wii
you can't unless there is an action replay code for it. The only ones i can think of that you can play as are Mario and luigi.
No, there is no such game as Paper Luigi. Although, Paper Mario: The Thousand Year Door does imply that Luigi went on his own adventure while Mario was in Rogueport.
Not that I know of.
No.
Mario
You be Luigi in New super Mario bros DS by holding L + R while choosing any save file.
Just get the Luigi badge.
To get Luigi go into the backyard and punch boos. When a cage comes out go towards it and search for a Luigi painting.
Its in the DS systems(Nintendo DS/DS Lite/DSi/DSi XL/3DS)
