I Think its Pokemon Diamond and Platinium
You see every single Pokemon, Google this "How to see every Pokemon in platinum DS"
you can find cheats for it at gamespot.com or supercheats.com.
If you mean for the Pokemon Modifier, use the caculater app on the Pokemon watch. You get it at Jubilife city. :)
Use an action replay.
get an action replay for Nintendo Ds
you can only get darkria in Pokemon platinium if you get the wonder card that was a Pokemon event last year.
