I caught them all in red and yellow. Working on catching them all in crystal.
Used a gameshark for yellow and crystal, but I still technically caught them where as red version I did it legit. Some pokemon you actually can't catch in most games, such as mew. You'll have to glitch ta catch him. Of course you can trade to get him, but are you really catching them all if you trade? No, no you are not. You can catch them all using a cheat device or you can catch them all glitching encounters.
