The GB Hunter is an unofficial accessory that allowed you to play Game Boy games on a Nintendo 64. However, due to emulation issues, you're treated to a heavily compressed bar from one of famed demoscener Jeroen Tel's songs that loops endlessly in place of the game's normal audio.

It could also function as a GameShark/Action Replay for Nintendo 64 games.

An equivalent product was released for PlayStation 1 models with a parallel port, replacing the infamous background music with an audio CD player.

In Europe, the GB Hunter is known as the Game Booster.

The Game Booster, but not the GB Hunter, contains a built-in Game Boy game called Rebound Mission, that can be played by starting it up without a Game Boy cartridge plugged in. This game is a rebrand of a homebrew called Poke Mission 97, adding a SGB border and replacing the SRAM save with a password system. Despite the device's infamous limitation, Rebound Mission still contains the original audio.
