Red and Blue versions
This is only true information
Red and blue versions have only 150 Pokemon,
plus Missingno, plus Mew if you have gameshark. (Gameshark is the
only way to get Mew. All the other codes you have read to get Mew
are fake. I have tried them all.) That is all the Pokemon you can
get inside the game, no matter what anyone else says. You cannot
get Marril (Pikablu) or Togepi, even with gameshark. The only
"new" Pokemon you can get with gameshark is Mew.
Now, about the game. There are 10 cities plus
Indigo Plato. I am adding to Pokedex2000 about where to catch
each Pokemon. It should be done no later than July.
Here is a list of gyms, their trainera, badges, and where they are.
If you are looking for a list of
attacks a Pokemon can learn and at what level they learn
them at, I am making that in Poekdex2000.
