GBA Multiplayer games?

[Eco-Logic]

Hey all, I am thinking about picking up a GBA SP to take with me to E3 for the flight.  The friend I am going with already has one so I would like to pick up a game that we can both play.  

I already know I am going to pick  up Bomberman tournament, because we always played Bman groing up, and you only have to have 1 cart.

Any other rec's for multiplayer games?  Thanks in advance.

Just as an FYI, later this Summer we will begin adding in the GBA support for our Gold Guide.  We are evaluating PSP, Nokia, etc. for inclusion as well.  You'd be able to just "Gold Guide" it at that point.  Doesn't do a whole lot of good right now though I know.

Advance Wars, Mario Kart, Karnaaj Rally, any Tony Hawk game.... those are the ones I've enjoyed the most so far
