I know it isn't technically a pirate, but it's in the same zone as Codemasters or Color Dreams/Wisdom tree games.
So, whenn I shove the Shark in my GBC, with a copy of Pokemon (or Animaniacs), it shows the black stripe of death (like if it's without a game) and won't boot.
It boots when a game is put in, so I don't have a clue what's going on.
