i think your brother is talking about flash cart for the DS. i written a quick blogs about it, see here

 

so where can you download ds games

 

cant name names on here as its not allow. there are many websites on the net, just do a google search for ' ds roms ' or you can use torrents or emules. simply search for ' gamename.nds '
