yeh. get a flash card (if thats the word) and then you get osmehting to make it slot into your DS (or it already fits) and you just donwload the roms and sitkc them in and play away.
aint sure if its like one game per card (i dont think it is) but even though DS emulators dont work the roms are fine.
but give it till early 08 and a fully working Emulator should be around they can already run 2D games just when it corsses into 3D and uses more power does the emulators struggly and with that its only the speed that slows down (and sound)
i dont know too much about hacking i know its possible coz i seen people do it lol, either way dont waste the £120 you would pay on a bundle coz its nearly cracked in emulation lol
