It's not pretty lol. We tried to zip tie everything together to make it at least understandable haha

EDIT: Hijacking this post since there are a LOT of common questions. Oh and /u/smilenataliew is the wife :)

FAQ:

>How did you connect everything to the TV/What adapters did you use?

NES through Gamecube (bottom 4): We have a 4-input composite switcher (those Yellow/Red/White cables) between the N64 and Gamecube, connected to our TV's 3.5mm composite port (which looks like a headphone jack), which we convert with cables like these. We do not recommend a composite to HDMI converter, as the output (might) look garbled from older systems (it did for us).

Wii: Component cables to HDMI converter, then into a remote controlled HDMI switcher (switcher and controller can both be seen to the left of Kirby Amiibo/the Wii)

WiiU & Switch: HDMI to the same HDMI switcher

>Don't the controllers just fall out when you open the case? How are they secured?

The NES controller is resting on a WiiU controller stand, oddly enough!
The SNES controller is the most finnicky. It's slightly leaning back on its own cords, but it's hard to get it to stay put.
The N64 controller is leaned against a stack of N64 games--it's definitely the system my wife and I have the most games for already!
The Gamecube controller is leaning against two other stacked gamecube controllers.
The Wii controller is just just leaning up against a thick piece of cardboard (more cardboard is also holding up the NES and SNES systems since the bottom of their doors would block view of the systems otherwise. My wife intends to wrap all cardboard with contact paper to make it all more decorative, she's very crafty!)
The WiiU has the same controllers as the Wii, except for the screen one, which is on a stand that actually charges the unit while it sits on top of the WiiU system!
The Switch controller actually stands on its own with the joy cons connected to them, but I've decided to actually show the charging station we bought with the joy cons connected to it so that they'll always be charged and ready to go!

>Where are the games?

Behind the controllers! In fact the N64 controller is leaning on a stack of them.

>Cable management? Do you have controller extenders?

Lots of zip ties in the back, and as for controller cables, we bought ~100 of those velcro straps for cords so we can wrap them up for neat display storage without wrapping the cords around the controllers. We also have extension cords for all corded controllers since the consoles don't exactly come out of the unit!

>Where can I get the display case?

It's a piece of furniture so it's a bit expensive, but it's definitely what we wanted after searching for a couple weeks! It's on Amazon

>You could have just emulated it all!

I love having and playing on the original consoles, but emulation is also awesome!

>Where's the Virtual Boy?

It doesn't connect to the TV so I didn't feel the need to get it for this project, but I DO want it for my collection! (Also kids should wait a bit before they play with a 3D device, even the 3DS)

>Where's Nintendo's even older console, the Color TV-Game?/Where's the 64DD?

Those were released Japan only, but I might still want to get them! I believe the controller and the console for Color TV-Game are both one unit, and space is limited, so it might be tough to integrate it if I want to get it!

>Where's the TV? CRT??

Mounted on the wall above the mantle. Sorry, no CRT...yet.

>PHOTOSHOPPED!/I swear I saw this before!

lol why would anyone photoshop this? Definitely real. I'll provide a few more images if I can. And definitely my setup! Though I'm sure I'm not the first to do something similar.

>lol fake niece

The niece and story are real, but if I'm being perfectly honest this is more for me than her haha
