I begin a new game and i have found some errors : 1) in the pallet town after prof oak gives my first pokemon, i have to speak with my mom and when she says me about that the prof oak let me in my room the pokeballs and potions she says the word "venture " and she should say "adventures " 2) in the viridian maze when i get the tm 23 (dragon rage ), it says that i found 2 tm 23, but in my backpack there is only 1. 3) the pokedex says that charmander in the lvl 16 learns dragon rage, but my charmander dont learned nothing. I was in the lvl 15 and i fight with the npc ash ketchum, and i kill his pikachu and pidgeotto and i up to the lvl 16, and charmander dont learn nothing, and when i beat to his butterfree charmander up to lvl 17 andd ont learn dragon rage. Charmander dont learn dragon rage, i use the tm 23 to can teach dragon rage to him.
