NOBBLE HAS STEPPED UP TO THE CHALLENGE!
My entry build is Officially Titled: Nobble's RetroPie Futureboy
It is a portable emulation handheld resembling the well-known Gameboy with features NEVER BEFORE SEEN BY MANKIND! Based on the Raspberry Pi 3 and running a custom version of RetroPie from tweaks I made.

The handheld case is a custom mold for a Nintendo Gameboy DMG made by Kitschbent. I will be modifying the insides to make it more roomy for the components.

I am using an almost fully stock Raspberry Pi 3 that will have a hat screen attached on top. The only modifications I will do is removing one set of USB ports for hard wiring components.

I am using a 3.5" HDMI touchscreen "hat" for main display. GPIO will control the touchscreen panel. ON TOP OF THAT I am adding in a pico projector you can switch to, that will illuminate gameplay onto any surface of your choosing. That will be housed inside a Shark MX cartridge made by GameShark. It was a modem cartridge for internet access and email on the gameboy. Service was called GB-Mail. I'm sure it was indeed terrible.. CUE THE MEMES.

I will be using an Arduino Pro Micro that will be setup as a USB gamepad with a layout seen commonly on most controllers these days. Dual Analog thumbsticks and dual triggers along with the usual d-pad and ABXY, Start, Select. Will be using @sotasystems Arduino program. I need a few 3D printed parts to install the button wells and button supports with ease. *Thanks Spencer!

The goal is to have a working stereo audio Amp connected to the Pi so that when I insert headphones into the jack, the audio cuts out and goes to headphone line. I may end up going with mono, time will tell.

I am using a 3.7v 7000mah Li-Po cell that will be connected to a portable battery bank BCM PCB to regulate power at 5v 2.1A to power everything. Charge port will be Micro USB and I expect battery life to be around 3-6 hours.

I will be adding Programmable RGB LEDs all over inside the case so you can hail a UFO from space. What is a Futureboy without some new age colorful tech? I will be either programming them from the Pi itself, or arduino. I also have a silicone cover to finish off the build aesthetically. It slides snugly right over the case for added protection.
