There's something I can't understand: 1. Moonshell and some homebrew like DSorganize can play another homebrews but can't load commercial ROM 2. Flashcard as R4 or Acekard, DSTT (perharps all of other flashcards) can soft-reset commercial ROM but can't do that with homebrews So why? They are all application which end with ".nds", what's the difference???
