Go into back of Poke mart
First go to Viridian City ( I am not sure, the one with the gym with Giavonni in it) and go into the Poke Mart, then you MUST save your game (or your game will crash and restart itself, it happend to me =P) then buy 99 pokeballs ( they MUST be pokeballs or it won't work) then press 'B' and you should be able to walk "behind" the counter and you can't get out... Solution restart the game and load ( I am not sure if it will reset your game so make a new guy and play through until you can buy 99 pokeballs and remember DO NOT SAVE YOUR GAME!!!!!) I have no clue if this is any help to you guys but I thought I would post it anyway.
P.S. PENGUINS ROCK!!!
P.S.S. (lol) I LIKE PIE
THANK YOU
