Open-source Game Boy flash cartridge using a Xilinx CPLD as the memory bank controller.
What is Nekocart?
NekoCart is an open-source flash cartridge for the original Nintendo Game Boy that uses a Xilinx CPLD as the memory bank controller instead of proprietary chips. It provides a transparent, customizable hardware solution for loading and playing Game Boy ROMs on original hardware. The project addresses the need for accessible, modifiable flash cartridges in the retro gaming community.
Retro gaming enthusiasts, hardware developers, and electronics hobbyists interested in Game Boy hardware modification and open-source hardware projects.
Developers choose NekoCart because it offers complete hardware transparency under the GNU GPLv3 license, allowing for customization and community improvements unavailable in commercial flash cartridges. Its CPLD-based design provides flexibility that fixed-function MBC chips cannot match.
