My new portable gaming rig(r/gaming)
For those wondering how to get this to work, you need a high tier android device (or anyone android device that has the hardware to run this, my phone is a Samsung Galaxy S3), a micro usb to female usb adapter, a usb hub, a game controller, the application called n64oid, and roms (I got mine from emuparadise.org).
EDIT: More detailed instructions
I downloaded an app called n64oid only found on the slideME market place for 5 dollars I think, you may be able to find a substitute on the Google Play Store though. Then I went to emuparadise.org to find the roms I wanted to play and downloaded them to my sd card. Next, I launched my n64oid application and found the rom in my downloads directory and opened it up. If you want to use a controller, then you have to buy an adapter. This is the one I bought: www.amazon.com/LIFETIME-WARRANTY-Electronics-Micro… You don’t need a USB hub but if you plan on using multiple controllers for multiplayer gaming you will have to buy a hub. You can also connect a usb drive, keyboard/mouse, external hard drive, etc… (not sure if all these will work on your phone though, but on my galaxy s3 they all do). Then buy any USB controller and connect it to your phone’s micro usb slot by using the adapter (xbox controllers work too, I think PS3 controllers might work as well). Lastly, map the keys to your game controller and play =D
