A while back I got a DS Lite from a friend and as soon as I got back home I googled ways to hack it. After not finding anything I was really looking for I came across this lovely little product. A flashcart or flash cartridge. These are reprogrammable cartridges that you stick into devices and run your own games, programs, or ROMS. When I was a kid I wanted one for my gameboy but never got it. And now, here I have one for my DS.
