Pokemon Black 2 Pokemart Codes

[Meepoe]

So bassically im not sure how to use it. All it says to do is press L and R. It gives you 634 master balls and a 999 ultraballs. Then all it says after that is press L to chamge the item and cost. So when I press L it changes to a Reveal Glass instead of a pokeball but thats it. Is it like the pokemon modifyer where you drop master balls equal to the pokedex number to make it work? If so wheres the code list to use as a reference?

That sounds like the wild pokemon modifier...

Exactly but how do I know how many master balls to get rid of to get the item I want
