To clarify, does it matter if the emulator runs on Linux or MacOS? Unclear if you were asking about two different things or planning to use them together.
There is a Debian package for mednafen:
http://packages.debian.org/sid/mednafen
InfoNES, if I'm not mistaken, has also been ported to PowerPC Linux.
downloading yellow dog 6.1 right now, and for it to work on linux
You might be able to find that out at iFixit.
Trying to find a linux distro that works on powerpc mac and a nes emulator that isn't nestopia which requires a plugin which you have to pay for just to use a controller
Don't use that, it won't work!
Try Debian.
downloading debian right now , didn't really even try yellow dog since it didn't have a live version to test and see if things worked before installing it.
so I got debian installed, but how do I run fakenes? I'm new to linux and tar.gz pls

I don't think there is a Live CD for Debian PPC--only i386 and AMD64.
Debian 7 Stable (Wheezy) runs very nicely on my MDD. I have been usiing it for online credit card purchases and such, since early Summer. PowerPC is an officially supported architecture on Debian.
Lubuntu 13.04 also works well on my MDD. However, Lubuntu 13.10 (the current testing version) has been broken on PPC for nearly 2 months now, and currently won't install at all. 13.10 Live CD also will not boot.
So, I'd recommend Debian, if it runs the applications you are interested in.
Honestly, MintPPC is the easiest distro to use on PowerPC. It "Just works". The website is here: http://mintppc.org/. Go to the "Installation Instructions" tab to find out how to install it. You will need an ethernet connection to run it, and the status of Firefox on PPC Linux is a bit iffy for the future, but you can just go to the Synaptic Package Manager and install a NES emulator, no technical knowledge required. Although I use Mac OS X 10.4 on my iBook, MintPPC is a good alternative.
