Hi I am a complete novice where this is concerned. Basically I want to be able to download DS games for my sister who's kids both have DS lites (she's sick of paying £30 a game) How do I go about doing this? As far as I can gather you can buy these r4 cartridges and a micro sd card then download the games and drag and drop them onto the micro sd card. Is that it? or is it not as simple as that? Is there some sort of idiots guide to downloading games and getting them on a cartridge? Any help would be appreciated. Thanks, Pete.
