I want to say thanks to the guys that helped me, because now it makes sense. I completely forgot about that Unknown Cave in Cerulean City! I remember it completely I'll get to it as soon as possible. Kenny2x4 said something about duplicating the master ball. Thank God I didn't use it on those three bird pokemon. Thanks fer you're help, appreciate it, especially the one on how to get to that one room in that Ghost Tower thing, it helped! So now my question is:
What's the duplicating cheat thing so I can finally get that guy?
And what is the Mew cheat thing? I'm ganna try that out.
