Emuritto is the Japanese name for Mespirit. So emuritto is Mespirit, to answer your question. :P
Sorry, but no.
nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
weaken mespirit a bit and use dusk and quick balls you might be able to use heal balls on it
catch them from there lakes then mespirit will run away so maybe use a materball
After you've released Uxie, Mespirit and Azelf from Team Galatic HQ, go to Verity Lake. Surf across to the cave. Inside you'll see Mespirit. Talk to it. After it runs away, it will be roaming the Sinnoh.
Here is a walkthrough on how to catch Mespirit: http://www.youtube.com/watch?v=ee1-2AU0k6w Do exactly what he tells you to do!
for example:this is how you get mespirit: so after you beat it you beat the game you go back to mespirit {its in the same place} you battle it. if you win it mespirit will ask to be on your team. say yes and TA DA!!!!!!!! mespirit is on your team. same with dialga and palkia and some other legendaries. some will just ask to be on your team.
