: You can't get a blank DS Flash cart at the moment, but it's probably an
: eventuality. It happened with the GBA. You can get a passme that
: redirects the DS to a blank GBA cart and run homebrewed programs,
: but it's bulky, and looks flimsy.
You can use the passMe to do a one time firmware update allowing you to run homebrew code from a gba flash card without any extra hardware. It currently seems pretty unlikely that there will be DS specific flash cards (which is good, because it helps keep the warez kidz away.)
: There is something coming out called the NeoFlash , which looks legit
: enough, but there's some speculation as to weather it's an authentic
: product, or not.
The NeoFlash is just a commercialized version of the passMe that includes a gba flash cart.
