From the project
Cart slot adapter to use Game Boy cartridges on MegaDuck consoles
The consoles have near identical cpu cores (1) and an almost identical cart pinout but a different edge connector style (Game Boy: one-sided, MegaDuck double-sided) and different cartridge widths (MegaDuck cart slot is narrower). This adapter allows plugging GB carts into the MegaDuck Console.
*1. But with modified register addresses, values and other changes to make the MegaDuck incompatible.
