A tip.

Here's something all newbies to emulation ask:
Q:Does an actual Xbox360 emulator exist?
A:No,currently there aren't any actual Xbox360 emulators.But I've heard from an anonymous source that a Xbox360 emulator is in development,but I think that the source cannot be trusted,as I found it on 4chan.

Q:Is there a Nintendo 3DS emulator?
A:No there isn't,there are a lot of fake sites that lure newbies and make them think that it's a legit emulator,but it's not,don't download it,and block the websites.

Q:Is there a PS3 emulator?
A:Actually there is,but it's in a very early stage of development,and currently can run only small homebrew games.It's used as a development enviroment for Homebrew devs.The emulator is called RPCS3 (Google it)

Q:Is there a Wii U emulator yet?
A:No,there isn't.The console came out not so long ago,and therefore we shouldn't expect an emulator.
