Squareboi
Squareboi is an open hardware cartridge system for the Game Boy Color, made to be as accessible and DIY-friendly as possible. Using a handful of off-the-shelf components, it provides the same functionality as an original cartridge, compatible with the majority of programs. Additionally, an Arduino-based programmer allows for easy transfer of games and save data.
Features
Up to 4MB ROM/32KB RAM storage space
Stores save data without needing a battery
Made of common, off-the-shelf parts
Fully compatible with MBC1 and MBC5 mappers, partial support for MBC2 and MBC3
Programmer works as a general purpose cartridge reader
Easy to build: A basic version can be made with entirely through-hole components
Powered by a single 5V rail
Compatible with third-party programmers, like the widespread GBxCart RW
Manual
A thorough explanation of how the system works, and how to assemble it, can be found in the manual file, HERE.
Acknowledgements
Squareboi's existence is only possible due to the continued efforts of multiple individuals dedicated to reverse engineering and documenting the Game Boy hardware. A full list of those whose work I've built upon can be found within the manual.
Still, I'd like to say it again: Thanks to all of you! I wouldn't have gotten here alone.

Questions
How big is the ATF1502BR PCB?
It measures 60 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATF1502BR use?
31 parts. 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 ATF1502BR KiCad files?
From the ALXCO-Hardware/squareboi repository on GitHub, at the commit this page was made from: the board is Hardware/KiCad 6/ATF Devboard/ATF1502BR.kicad_pcb and its schematic Hardware/KiCad 6/ATF Devboard/ATF1502BR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATF1502BR design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
