The Universal Mega Dumper v3 project is an open-source solution for cartridge dumping and writing.
This PCB interfaces a Gameboy / Gameboy Advance cartridge to the UMDv3. The UMDv3 Main PCB detects which cartridge adapter is currently connected by reading an ID byte on the I2C bus provided by an MCP23008. The ID byte and cartridge voltage are selectable via pin header:
- Gameboy Advance ID - 0x04
- provides 3.3V to the cartridge
- Gameboy ID - 0x05
- provides 5V to the cartridge
Please refer to the UMDv3 Firmware Project Repository for UMDv3 documentation and instructions; this is the project's central repository and where the wiki is hosted.
All components in this PCB depend on my KiCad libraries which are available here on github. I don't use any pre-existing libraries - fight me.
