‘The game started with the familiar Nidorino and Gengar intro of Red and Blue version. However, the “press start” screen had been altered. Red was there, but the Pokémon did not cycle through. It also said “Black Version” under the Pokémon logo…After selecting your starter, if you looked at your Pokémon, you had in addition to Bulbasaur, Charmander, or Squirtle another Pokémon — “GHOST”.
…Defending Pokémon were unable to attack Ghost — it would only say they were too scared to move. When the move “Curse” was used in battle, the screen would cut to black. The cry of the defending Pokémon would be heard, but it was distorted, played at a much lower pitch than normal. The battle screen would then reappear, and the defending Pokémon would be gone. If used in a battle against a trainer, when the Pokéballs representing their Pokemon would appear in the corner, they would have one fewer Pokéball.
The implication was that the Pokémon died.’
