well u need an r4 /m3/dstt(something like that) some flash card like that i got an R4 u can get these at www.dealextreme.com for like 30-45$ (but i got it at pacific mall /if you know that mall...) after u get one of these then u don't need to even buy your ds games /for cheats like all cards just get a usercheat.dat/CHEAT.dat and put it in ur ds wit those AR codes and thats it!!!!
