you need: -a passme (to be able to run homebrew in ds mode) -some kind of flash adapter (g6, supercard, m3, etc...) -some kind of flash card (consistent with the type of the adapter) -some kind of reader/writer (to write/read data from/to the flash card) and a ds of course xD u'll have to save the homebrew u want to use in the flashcard, put it in the adapter, plug the adapter to the gba slot, use a passkey with an original game, and turn on your ds xD depending on the adaptar, ull have diferent kind of menues, but from there, u can execute homebrew (any kind, dslinux, pointyremote, win2ds, etc....)
