Recomend a DS Download-Play game?

I'm talking about the games that offer multiplayer and do not require two game cards. Seeing as official "nintendo" download play games don't work on my R4 I'll need some that will. (:

Check out: http://wiki.scorpei.com/index.php/R4_compatibility_list to get a list of compatible and incompatible DLP games. Also make sure you are using a fast, and legit MSD card you are using. If you need further assistance then just ask for it.

Thanks for the link! Very helpful. ;)
