Game Boy software: This is the Pokémon Blue cartridge. This is a cartridge-only listing; there is no outer box or instruction manual. The data for Mew, distributed at Nintendo Space World '97, is included, unraised. I accompanied my child to the event at the time, and since you could get two Pokémon with one right if you had two cartridges, I left one of each as they were. The item will be shipped in a bubble-wrapped envelope.
