README
README.mdUMDv2
The Universal Mega Dumper v2 project aims to be a complete open-sourced solution for cartridge dumping and writing. It includes a very performant MCU which has a direct memory connection to a generalized databus consisting of 24 address bits and 16 data lines. Along with a dozen or so control signals, it should be sufficient to interface with most cartridge types.
Cartridge Adapters
The UMDv2 by itself only includes a generalized connector with all its interfacing signals. Cartridge adapters must be used in order to interface to the physical media. All cartridge adapters, as they are created, are added to this project as submodules and will be linked in the CartAdapters directory.
Cartridge Adapter ID
Each cartridge adapter has an MCP23008 on the I2C bus which identifies the console type for the adapter and thus prevents contention on IO.

Dependencies
Parts Libraries
All components in this project depend on my KiCad libraries which are available at https://github.com/db-electronics/kicadlib . I don't use any pre-existing libraries - fight me.
Firmware
There are two firmware components associated with this PCB: the STM32 fimware and the PC-side client. Both are available here:
Please note that version 2.0 is in its absolute infancy, don't expect to find any working releases in the firmware links above for the time being. The links are for provided provideness for completeness of documentation.

112 parts, built around the STM32F413ZHT6, AZ1117CH-3.3TRG1, MIC5504-3.3YM5-TR and 0.1UF 50V 5*11. 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 UMDv2 KiCad files?
From the db-electronics/UMDv2-kicad repository on GitHub, at the commit this page was made from: the board is UMDv2/UMDv2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the UMDv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask db-electronics before reusing the design.
