Hi everyone:

I would like to find the way of How to develop a NES emulater on iOS ( Maybe include other OS just like Android ..) Just like NES 3.
So, I was hoping that somebody here might have some experiences or suggestions that could point me in the right direction.

Thanks.

You could take a look at the source code for Macifom.

As the developer of Macifom, I would have to agree. It doesn't take more than a few hours to get the desktop code base working on iOS.
I have my own port to iOS that I use to publish NES games on the App Store (e.g. Zooming Secretary). It has a specially tuned renderer that I'm currently keeping to myself, but otherwise it's exactly what's up on the project page. I push all fixes to the emulation core upstream to the open-source project as well.
If you're interested in participating in the Macifom project, just PM me.
