In my waiting (boredom) time of receiving the first run of of the 2.2" & 2.8" version PCBs from China,
I have created and uploaded a 2.8" version using a raspberry pi 3. it's a little taller and wider, but this one also feature an accurate DMG (Gameboy) layout... ...eventually wanting to create a Acrylic / Plexi laser cut case
LMK what you guys think of this one.

This version would use a female header on the board and simply plug and play. that way you would not be committing your Pi for life
I will later replace the 40 pin header with an SMD Female Header Socket (or you can just use Kapton Tape)
The GitHub repo in my signature is always up to date
You thought of using pads so you can get the retro feel of the rubber domes?
i have, and that's a great idea, since that would reduce cost by using capacitive buttons.
what i will probable do after the initial short run is overlay the capacitive touch and tactile switch on the foot print

Big Update Gameboy Zero - Handheld Edition (More Size)
Hey all, if you have been following this thread, you will know that there are a few sizes i have created.
There are now 3 display size versions (1.8", 2.2", 2.8") and two platforms (Pi3 and PiZero/w)

As well, currently working out a plexi (layered) solution for the Pi3 version (PiZero cases to follow)

I should be getting the first test batch of PCBs from Seeed Studio next week and will soon put up working prototype videos and review.
Lastly, i have added the Eagle CAD library for the Displays
Pre Weekend Update Gameboy Zero - Handheld Edition (Semi Official Design)
So after tinkering with the smaller 4.2mm outline buttons i have found that once i have them in hand, it's too small.
Iterating on the project, i have netted out that the 2.2 ILI9341 will suit it the best
The d-pad buttons are now 6.2mm outline tact switches, rotated 45 deg and laid out in a diamond formation.
The primary buttons (ABXY) are now matching the 16mm offset of the standard DMG layout.
The shoulder buttons (L1/2 R1/2) are now lower on the back panel and have been placed in an ergonomic fashion.
This was done in order to accommodate a simple 2 layer plexi case (to be designed)
Check out the pics, let me know what you think (for some reason the Pi Zero tPlace layer shows up on the tPlace of the pcb in printing, but won't be so on the final stencil)

the cost... ...i'd be looking to get $20-25USD per populated board.
why so cheap?
well.. ..i know you will have to buy a few of your own parts (listed in what's NOT included above)
