Basically, I'm trying to build: a dual joystick, 14 button Retropie system with a full sized Pi 3B...all "Tetrised" inside a Game Boy Color shell. Here is the front:

The inspiration for this project comes from my first completed build which is pictured below. It's basically what Wermy did in his 2016 GBZ guide but with a GBC shell.

Pi Zero W + 13mm heatsink
Adafruit 2.5" composite screen
Camble's Safe Shutdown v1.2
Adafruit Powerboost 1000c
Adafruit 1200mah LiPo battery
Black Kitsch-Bent D-pad/ABXY buttons/power switch
Bottom half of GBC motherboard for button input + copper tape for X and Y
Two 6x6x7mm clicky switches for LR
Helder's 5v power strip
Helder's surface mount PWM buffer
1" Adafruit speaker
PAM8302 mono 2.5w class D amp
10k potentiometer
30 AWG for data and 24 AWG for power
--------------------------
So yeah. As it stands now, everything is moving along nicely! Basically all of the hardware does fit inside comfortably after some modification, and I even managed to fit a 3000mah (605085) battery in there.
There are a couple problems that still need to be solved such as the rear button placement and some wiring, but it's only a matter of time before this thing is completed.
