An error handler that notifies the player when the contacts on the cart become misread; obviously this will never appear on a Game Boy since the game would lock up upon reading a bad opcode and this message was likely displayed on test equipment. Specific Super Game Boy palettes do not exist for this screen and will display the prior screen's setting. Gameshark code 010F90FF will display the message on any screen
