Lots on line in the Gold & Silver area now ... including the huge group of ELEMENTS pages (fire, water, psychic, dark, steel, etc.), each of which has a double Pokédex including all elements for Pokémon in the red, blue, yellow, gold and silver games.
The new Gold & Silver Pokédex is here and the original Gold & Silver Pokédex is here (for those of you who might wish to access the individual G + S Pokédex pages for the first 151 pokémon).
The new Red, Blue & Yellow Pokédex is here, with the first edition here. See below for details of all the other seven pokédexes which have since gone on line.
Other Gold, Silver + Crystal areas include: Towns, Gyms & Badges and HMs, which are now being linked to references on the 'Cheats + Help sent in' pages, and Pokémon Gold + Silver Evolution.

A lot of mail has come in relating to the Gold and Silver versions, and the new table below (further down) allows us to add links to all relevant items in the "Cheats" area, so visitors can find specific info about the Gold, Silver and Crystal games. See the Gold & Silver Walkthrough also.
We've now made a total of TEN new pokédexes, which you can access from the table below - masses of cheats links have now been added - note that you need to click on the *name* of the Pokémon (within each dex) to get to the one where it originally appeared, which will have any cheat links included.
You can still reach the original RBY, GSC and RS dexes from links on the new pokédex page for each of those, and both sets of the red/blue/yellow and gold+silver pokédexes also have individual pages for each pokémon that you can access by clicking on the pokémon name within each relevant dex.
... eg if you go to the Pokémon Platinum pokédex and click on Charizard, that will take you to the Red/Blue/Yellow pokédex (where you'll find the cheats links for Charizard) - then if you click on Charizard again, you'll get to the individual Charizard page.
CHEATS: The main "Cheats" area (including all cheats, tips and shortcuts now on line) is here - those relating to Gold, Silver + Crystal will be linked from the table below.
There are also new areas for cheat links by individual game version: Pokémon Platinum, Diamond + Pearl, Pokémon Stadium, Pokémon Colosseum, Pokémon Ranger, Pokémon Crystal, Pokémon Emerald, and XD: Gale of Darkness, as well as the existing ones for Fire Red Leaf Green, Ruby/Sapphire, Gold + Silver, and Red, Blue and Yellow.
Please note: The links from the table below may not be updated until all the Cheats additions are completed, but you should be able to find any new entries, until then, by using the new Cheat-Number page links (those in orange) from the table at the top of the Cheats index page, or the follow-on links at the bottom of each Cheats page.
