mario vs donkey kong miniland mayhem

hi :D i just downloaded Mario vs donkey kong mini land mayhem and it's not working on my ds
my flash cart is r4 sdhc ...can anyone help me ? .. thank you :D

Here is the solution : Wait for an Anti-Piracy patch, or for a flashcard patch.
You should read the board too because it's the third thread concerning this game.

i made a topic about this all ready.
