Installing Zsnes and SixtyForce on Apple TV

Hi all,

Can anyone please explain how to install these emulators using a mac?

I’m new to a mac, so it’s a little bit hard to learn. I’m using Cyberduck to ssh into my apple and i can upload/delete etc. But how can I install a DMG. If i doubleclick on the dmg it installs it on my mac, I cant choose where I want to install it/??? Is there a way to do this. IF anyone can help or give me a link to a site that can help me step bu step, It will be very much appreciated!!!

Thanks in advance everyone!!!
