FWNitro

From PHWiki

FWNitro is a purely homebrew firmware for DS.

It's an alternative to using FlashMe, which is a hacked version of the original DS Firmware.

FWNitro can be used to dump roms onto most CF-based adaptors, including the Supercard and GBA Movie Player. Unlike NDS Rom Dumper, FWNitro produces a usable .nds file.
