1.you need a flash card first, then insert the memory card into the USB port on ur pc, then drag the game files to the pop-up which should say removable disk.

2.You need to buy a flash cart, such as an R4DS or CycloDS (which costs about $30-35USD or $50AUD. They have a memory card in them so they can play games, so you just have to connect the memory card into the computer and drag the files after you get the flash cart. If you already have a flash cart, go to the website of the cart and look at their instructions on how to upload the games onto your DS.

B.T.W. They should be .nds files only, and not .iso.
