Different emulators?

[Wazoo]

Are there any emulators on the webs that I could download (other than the paid ones on the marketplace) that work pretty well? I'm all down for paying for apps and stuff to support the devs but it would be cool if there are free ones out there that work just as well. I figured I'd ask here first instead of googling it without knowing what to really look for.

Edit: Talking about game emulators if that wasn't already implied

The "lite" versions of nesoid, snesoid, all the other *oid emulators work fine. The only thing you can't do with them is save the rom state.

(you're in the wrong subforum, this is an app question)

And why? googling it would get you an answer in a few minutes compared to the hour and a half it took to get 1 response here.
