ROM Help

I have an R4, for my DS. I tried to put some of the ROMs on it, including Kingdom Hearts 358/2 Days, and Mario and Luigi: Bowser's Inside Story, Mini Ninjas, and Pokémon Platinum. Only Mini Ninjas and Pokémon Platinum actually work. Kingdom Hearts will let me set up my file, but then the screen goes black before anything actually starts. On Bowser's Inside Story, I press, "New Game," and it doesn't let me press anything. Anyone know what's wrong?

kingdom hearts and mario and luigi have anti piracy

Both also have sticky threads:
