Yes there are downloads for Nintendo DS Lite. Clearly not legal and you need some software and a special card called an R4 or the equivalent to interface to the DS. You can buy the stuff on Amazon and if you look for torrent sites you will find ds games with .nds file names. In my view this is why Nintendo have revised the Lite to the DSi, sadly for them there is already a way around that too! Answer; Make the games cheaper as most are low quality and not long enough to justify the price.
