Geeky week

It's been a while since my last post. Been traveling for work and it has been difficult to make time to write. Today though I picked up a new Raspberry Pi II B and have decided that I want to make it into the ultimate emulator box. I'm sure my wife is tired of all my old gaming systems sitting out. I'm going to set them all up on my Raspberry Pi.
The biggest things I feel I need are the following
1. Portable - When I travel I would like to be able to take it with minimal weight added to my luggage.
2. Wireless control - After this is setup I will need to make sure I can control it through wireless, it is too much trouble to have wires strewn around my hotel room.
3. Basic games - I really only care about having Zelda, Mario, Final Fantasy, and arcade games. I own most of these so I need to look at how I can license those I do not own. I have every Final Fantasy and Zelda game, need to pick up super Mario world as that is the best super Mario game. Also Super Mario RPG as well.
4. I need to figure out N64 controls. The N64 controller is out of the question as it is the time Nintendo forgot that children do not have 3 arms. On a plus note during the apocalypse the N64 will be ideal after the fallout.
5. Battery Powered - This is less important, I think I have battery packs from my pineapple that should work fine for this.
6. Wireless - Taken care of have my wireless cards I use for kali linux that I carry with me anyway. This gives me access to my high DB antenna.
7. Optional - Would be nice to have a small display, at least 5" preferred. Touch not needed on this.
8. Light case - Need something ultra light that will keep all of this protected. Maybe design and print this one would be the best option.
