How do I put a game on a SD card?

Can you put a game on a sd card because I have a dsi and I want to be able to play games off an SD card can somebody help me if theres a way to put a game on my Sd and micro! ???

The DSi cannot play illegally downloaded games from the SD Card.
But you can play games downloaded from the DSi Shop, these are stored on the SD Card.In order to play games downloaded from this site on your DSi, you must have a DSi compatible flashcart. Like the Acekard 2i.

I might get that for christmas,but why can't you play illegally downloaded games with the dsi?

Because Nintendo want to make money, not lose it.

Oh but can there be a way to put a game on an SD card?

With an Acekard 2i (or another DSi flashcart) you can put games on a MicroSD and put the MicroSD inside the Acekard, and play it like you would a normal game.But you cannot play them from the SD Slot on the DSi.
