Pocket PC emulation

Ok i have been trying to find a good PPC emulator but the only thing i keep coming accross is the MS development tools and these seem to be no hlep at all. I downloaded them 86megs and installed but all i was left with was a bunch of files and nothing that could really help me. The only remotely nice thing i saw in all these files and folders it installed was a ppc skin. But no .exe that would open or looked usefull. So im asking anyone that is emulating the ppc on there pc how do you get htis thing to work?
