Missingno has a pokedex entry!
I started a new game in blue verision and I used my Gameshark to get master balls, surf, and fly. Then I flew over to Cinabar and did the glitch. Instead of running I caught "M" not missingno and the pokedex poiped up after I caught it. Everything on the page was messed up and it showed a rydon but it said I caught an "M". It also had a cry that was very long, about a minute and a half. Do you think gameshark had anything to do with it?
