Does any body remember the red and blue version of the Pokemon gameboy game?

Question

I found my old red version yesterday and I cant remember how to do 2 things on it. I cant remember how to get Mew, and how to get into Bill's back yard. I have done both before, but I cant remember how. Can any one help.
