To get 99 of the sixth item, go to your items by pressing start and put something in the sixth item slot. Then go to Viridian City and talk to the by the Gym that shows you how to catch a Weedle. When he ask if your in a hurry say no and he will show you how to catch a pokemon. Then fly to Cinnabar Island and when you apear infront of the pokemon center don't move down or left, just move right all the way over to the water then surf. Next surf up and down. Stay closest to the land and you should run into a Missingno.(WARNING DONT CATCH IT. IF SO THE GAME WILL MESSUP AND DELEAT POKEMON.)Instead run to land and look at ur sixth item it should have a (symbol)9.It means you have 99 of that item. You could do this with nuggets and sell them for 999,999 dollars but if you wont more cash save one nugget and repeat the process. Missingno is part of the system is looks like a bar code when u see it. Missingno is the save,grapic,pokemon control if cought the game will messup! So be careful!
