Homeboy is Raspberry-Pi based Game Console(Emulator) which can also act as server( or Backend) for my other projects.
CAD Model:
Everything fits together [Will be forced to Fit ;) ]
It has 3 separate printed pieces. The Base, the Enclosure to support pcb, and Switch to to turn-on it (😏).
Made in Autodesk Fusion.

Questions
How big is the HomeBoy PCB?
It measures 99.5 × 90.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the HomeBoy use?
62 parts, built around the AP3441SHE-7B, TF-CARD-9P, AP22653W6 and PZ2.54-2*7. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the HomeBoy KiCad files?
From the devisunofficial/HomeBoy repository on GitHub, at the commit this page was made from: the board is HomeBoy/HomeBoy.kicad_pcb and its schematic HomeBoy/HomeBoy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HomeBoy design in my own project?
Its repository states no licence, so its author keeps all rights: ask devisunofficial before reusing the design.
