1) INTRODUCTION
******************************************************************************
Pokemon FireRed and Pokemon LeafGreen were released by Nintendo for Game Boy 
Advance in North America on September 7, 2004.

This FAQ describes the Itemfinder, but is mostly a list of all the items 
available in Pokemon FireRed and LeafGreen that can be found using the 
Itemfinder.  The 158 (or so) items are listed by location, in the general order 
of a "typical" game walkthrough.

******************************************************************************
2) ITEMFINDER
******************************************************************************
The Itemfinder is an in-game Key Item that can be used anywhere within the game.
It allows the player to locate hidden items.  These items can be almost 
anything, from types of Poke Balls, to health items like Potions, to Berries, 
to other useful items like Moon Stones.

The Itemfinder will locate only items that are "on-screen" (within the window 
of your game).  If you are scouring a location to look for items, you will need 
to move your player around and use the Itemfinder often in order to check an 
area completely.

You obtain the item by directly facing the hidden item and pressing the "A" 
button.  In general, you can't get the item if you are standing on the exact 
spot where the hidden item is located.

If there are no items to find, you will get a verbal response saying, "... ...
...Nope!  There's no response."

Usually, if there is an item nearby, you will get a verbal response saying, 
"Huh?  The ITEMFINDER's responding!  There's an item buried around here!"  You 
will also get one of two audio/visual responses:
1) Two pings accompanied by two arrows, or
2) Four pings accompanied by four arrows
The number of pings/arrows indicate how close your player is to a hidden item, 
while the arrows indicate the general direction, relative to the player, of a 
hidden item.

If you get two pings/arrows, move two or three steps in the direction of the 
arrows and try again.

If you get four pings/arrows, first face the direction the arrows point and 
press the "A" button.  If unsuccessful, move one step in the direction of the 
arrows and try again.

In a limited number of places, if you are standing exactly on a spot where a 
hidden item is located, you will get a special verbal response saying, "Oh!  
The ITEMFINDER's shaking wildly!  There's an item buried underfoot!"  Without 
moving, press the "A" button to get the item.

******************************************************************************
3) GETTING THE ITEMFINDER
******************************************************************************
You get the Itemfinder from Professor Oak's Aide, located on the upper floor of 
the Gate at the eastern end of Route 11, where it connects with Route 12.

In order to get the Itemfinder, you must have 30 different Pokemon in your 
Pokedex.

By the time the typical player has reached the eastern end of Route 11, the 
following Pokemon could have been caught:

1) Bulbasaur, Charmander, or Squirtle, as a starter
2) Pidgey in Route 1 (or 2, 3, 5, 6, 24, and 25)
3) Rattata in Route 1 (or 2, 4, and 22)
4) Spearow in Route 22 (or 3, 4, and 11)
5) Mankey in Route 22 (or 3 and 4)
6) Caterpie in Viridian Forest (or Routes 2, 24, and 25)
7) Metapod in Viridian Forest (or Routes 24 and 25)
8) Weedle in Viridian Forest (or Routes 2, 24, and 25)
9) Kakuna in Viridian Forest (or Routes 24 and 25)
10) Pikachu in Viridian Forest
11) Nidoran(F) in Route 3 (or Route 5 trade)
12) Nidoran(M) in Route 3 (or Route 5 trade)
13) Jigglypuff in Route 3
14) Clefairy in Mt. Moon
15) Zubat in Mt. Moon
16) Paras in Mt. Moon
17) Geodude in Mt. Moon
18) Ekans or Sandshrew in Route 4 (or 11)
19) Oddish or Bellsprout in Route 24 (or 5, 6, and 25)
20) Abra in Route 24 (or 25)
21) Meowth in Route 5 (or 6)
22) Farfetch'd in Vermilion City (trade a Spearow)
23) Magikarp in Vermilion City (or Pallet Town, Veridian City, Routes 11 and 24,
    and Route 3 purchase)
24) Diglett in Diglett's Cave
25) Dugtrio in Diglett's Cave
26) Mr. Mime in Route 2 (trade an Abra)
27) Drowzee in Route 11

Any evolved forms of these Pokemon will "count" as well.  Usually, the starter 
has experienced one evolution.  You can get a Moon Stone in Mt. Moon to evolve 
Nidoqueen, Nidoking, Clefable, or Wigglytuff.  Pokemon that evolve "quickly" 
are Butterfree (level 10) and Beedrill (level 10).  There are also Nidorina 
(level 16), Nidorino (level 16), or Kadabra (level 16).  Lastly, you can trade 
to evolve Alakazam or Golem.

If you don't have 30 Pokemon in your Pokedex, you can always come back to the 
Gate later in the game.

******************************************************************************
4) BERRIES
******************************************************************************
You can find 15 of the first 20 numbered Berries as hidden items in Pokemon 
FireRed and Pokemon LeafGreen.  Actually, you can detect the "hidden" Berries 
without the Itemfinder.  There is a noticeable change in the grass design at 
the exact spot where a "hidden" Berry is located.  It looks like a darkened 
oval, possibly giving the appearance of a depression in the grass.

Here are the 15 Berries and their locations:

1) Cheri   - S. S. Anne, Route 10, Berry Forest (?), Sevault Canyon
2) Chesto  - S. S. Anne, Route 9, Berry Forest (?)
3) Pecha   - Route 24, S. S. Anne, Berry Forest (?)
4) Rawst   - Route 8, Berry Forest (?), Canyon Entrance
5) Aspear  - Route 23, Berry Forest (?), Water Path
6) Leppa   - Route 8, Route 23, Berry Forest (?), Six Island
7) Oran    - Route 3, Route 25, Berry Forest (?), Water Path
8) Persim  - Route 4, Route 10, Berry Forest (?)
9) Lum     - Route 8, Route 23, Berry Forest (?)
10) Sitrus - Route 6, Route 23, Berry Forest (?), Memorial Pillar
16) Razz   - Route 4, Berry Forest (?), Memorial Pillar
17) Bluk   - Route 25, Berry Forest (?), Memorial Pillar
18) Nanab  - Route 10, Berry Forest (?), Trainer Tower
19) Wepear - Route 7, Berry Forest (?)
20) Pinap  - Route 14, Berry Forest (?), Water Path

******************************************************************************
5) HIDDEN ITEM LOCATIONS
******************************************************************************
You don't have to use the Itemfinder to obtain the hidden items.  As long as 
you know the exact location of an item, you can face the spot and press the "A" 
button to get the item.

It seems that several of the hidden "value items" (e.g., Big Pearl, Pearl, 
Stardust, etc.) found in "sand" (Routes 20 and 21; Sevii Islands) appear 
randomly.  They may be missing one day, but will appear on another.
