Recently i bought a used version of Pokémon Black and this was on it. Sorry for the bad quality.

When i launched the game i thought it was legit. To me, nothing seemed off at first but then i looked in the box.

After the box i looked into the bag and there were three stacks of 900 Rare Candies.

as well as every TM/HM.

I then went into the tall grass, just to see what i got and surprise, it was a Combusken.

So yeah, it is safe to say that cheats were used on this copy.

All in all, a cool find.
