There is no possible way to get a Mew in Ruby or Sapphire. The only way to get one is from Nintendo events.
You can't catch it. You must transfer it with Pal park from your Pokemon emerald ruby or Sapphire.
mew cant be caught in ruby unless you have a game shark
the exact same on ruby and Sapphire
any move
Yes, you can. But, You have to have caught Mewtwo already, beaten the Elite 4 12 times and given the Ruby and Sapphire to Celio. Next, you go to the spot where you caught Mewtwo in Cerulean Cave, walk/run around some and eventually Mew will appear.
No it doesn't exist.

not every pokémon from Sapphire and ruby can be caught in emerald you have to trade or use cheats to get them all.
