From the project
A open Sega Genesis cartridge PCB
This projects uses a 27C322 4MB EPROM Chip and a FM1808 32KB FeRAM as save storage. It was developed in KiCAD and tested in real hardware.
In the actual state, this cartridge features:
- Suports Genesis and 32X software - ROM Support for up to 4MB - Save support for all ROM sizes (Selection for <2MB/4MB by jumper) - 32KB of FeRAM for saving - No need for battery for saving - Rudimentary ROM bank switch (Permits multiple games on same ROM)
