Power Up Basics (Virtual Boy)
The Virtual Boy is portable tabletop video game console made by Nintendo.
It is unique in that it looks like a modern VR headset from back in the 90s, with two red eye ports and when viewing games they appear in a monochrome red color.
The actual games and the visual you get when looking into the console is actually very good. Sharp, clean and great audio.

The Virtual Boy uses the same semi-common supply as the Game Gear (EU), Master System, Master System 2, Mega Drive 1, Atari Jaguar and PC Engine. That being a DC 9V (5.5mm x 2.1mm).
This power supply actually plugs into the controller, which then sends the power to the console.

Then the controller plugs into the Virtual Boy on the underside.

Insert the game into the front of the Virtual Boy face up.
Without a game nothing will boot. You will hear the speaker turn on but that's about all that will happen.

The On Off switch is located on the controller itself. Flip it to On to turn on the console.

Once turned on, after about 4 seconds you should hear the game load (presuming you have the volume wheel turned up located under the Virtual Boy on the left side) and your speaker, game and console work.
When the game loads if you look into the eyepiece, you should see the game load up in bright red on the screen.

Once the game first loads, you will be presenting with a Virtual Boy focus screen.

At this time, you can adjust the focus (moves the perspective of the screen closer or further away), and the distance between each eye using the inter-pupillary distance (IPD) dial on top.

I find as you adjust focus, your eyes first become unfocused then just refocus to the new distance, so this slider is mostly useless for me.
The IPD dial adjusts the gap between each eye mirror to alter the 3D perspective. Adjust this to the point where your eyes are the most relaxed feeling and not straining.
