Pokemon Blue Version

To get 99 of any item, first put the item you want to multiply in the sixth item slot. Now use FLY and go to Viridian City. Talk to the old man almost all the way north of the town. When he asks if you are in a hurry, say no and watch him catch a weedle. Right after that, fly to Fuchsia city. Make your way south and, when you you reach the water's edge, use SURF and make your way to Seafoam island. When you get to seafoam island, swim up and down the beach until you run into a Pokemon called "M" (a glitch like Missingno.) Once you see him, kill him or run away. DO NOT CATCH HIM! After that, you should have 99 of your sixth item!

Leech Seed is a move well-known for absorbing 1/16 of the target's HP and healing the user of the move by the same amount. However, you can actually boost this damage through the unintended effects of Toxic. When you use Toxic to Badly Poison a foe, and then use Leech Seed on them, Leech Seed's damage will also increment: thus, you regain 1/16, then 1/8, then 3/16, then 1/4, and so on, of your HP. Toxic will also be taking effect in this time, dealing the same amount of damage. In other words, you not only regain tons of HP, but also double the damage of Toxic, from one point of view.

To get onto the Cycling Road without needing a Bicycle, simply hold Left while the guard warns you that you must have the Bicycle to enter Cycling Road. (If you already obtained the Bicycle, this still works if the Bicycle is in the PC.) In doing so, you will bypass the guard; if you continue onto Cycling Road, you'll still ride a bike.

First go into the Safari Zone (SZ). Go into the area with the pokemon that you want(e.g. Scyther). After you're there, fly to Cinnibar Islands. Surf up & down the right coast, and eventually SZ pokemon will battle you there. If you need other SZ pokemon, just keep swimming up & down the coast. The effect of this glitch doesn't affect your saved game. If you get tired of swimming, don't get out of the water: instead, save right where you are. When you resume your journey, the SZ glitch will still be in effect. This glitch works with any area, not just the SZ.

To get WELL 99 of an item, put the item you want duplicated in the sixth item slot. Make sure you have the Fly HM, then Fly to Viridian City. Talk to the old man that stopped you in the begining of the game( kind of to the north) When he asks if you are in a hurry, say no and watch him catch a weedle.

Then Fly to Cinnabar Island, and use the SURF HM. Surf along the right COAST, Not in the water, if you surf in the water it won't work.

Now, use SURF until you run into a Pokemon called ''M'', ''Missingno.'', Or a Pokemon over level 100 Once you see one of those, kill it or just simply run away. DON'T CATCH THE M OR MISSINGNO. AS IT WILL RUIN YOUR GAME!!!

When fighting a high level M if you have a slow pokemon and it attacks you are screwed, as it has a VERY high attack, you can beat him by simply using a quick attack.

after you win/run look at your sixth item it should look VERY weird with wird symbols and such, don't worry all it means is you have over 99 once you use it up alot it will stop using symbols and once the supply gets back to 99 it will show up as ''99''
