Yes, but only by glitch, not hack, go to this website: www.ocf.berkeley.edu/~jdonald/pokemon/mewglitch.html
Just make sure you start a new file first...
blue mew is a shiny version of mew so you have to be very lucky to catch a shiny Pokemon let alone a shiny mew
Mew was a special event Pokemon that was distributed for Pokemon Red and Blue. Mew cannot be found in the wild without cheats or using glitches, which is still possible to obtain. Bulbapedia likely have a great summary about this Mew glitch in Pokemon Red and Blue.
it is not possible
Its possible if you have action replay. But if you dont have action raplay, its impossible to catch mew.
mew is not catch-able on red blue or yellow but its is possible to use glitches to catch mew http://www.youtube.com/watch?v=Y3jv1PKrF0Y mewto is catch-able, mew is handed out at Nintendo specail events and that's about all
Its not possible to get mew in firered only emerald can via Nintendo event.
The only way to get Mew in Pokemon Red, Blue, and Yellow is via the Mew Glitch, which you can find on Bulbapedia.

u can get him at the berred relic
In Pokemon Red, Blue, and Yellow you are able to catch Mew through a glitch. Mew is available in other games such as FireRed and LeafGreen, but it was an event Pokemon. The event it over, and all you can do is wait for a future event, or trade with someone who has Mew.
You can not get a mew in Pokemon Diamond without trading or cheating (HIGHLY NOT RECCOMENDED.) but there is a way to get a mew in the following games: Pokemon Blue, Pokemon Red, or Pokemon Yellow. look up "Mew Glitch" in Google search and find out how. hope this helped!
You cannot catch Mewtwo in Pokemon Crystal, but you can trade it from a Pokemon Red or Blue. Hope this helped :)
