Charmander and Squirtle are available via either Stadium or the Mew/Ditto glitch.
Stadium's the easier option if you've cleared up to the Elite 4 there, as you'll get a Pirze Pokemon each time you'll beat them.
Downside is, it's chosen at random (I must've had several thousand Charmanders now, but only 1 Eevee...) from the pokemon you're forced to choose between in-game (Starters, fossils, and Eeveelutions) --- Support PAL Gamers http://boards.gamefaqs.com/gfaqs/genmessage.php?board=7&topic=20140880
