What this project is about:

This is a VHDL implementation of the Bandai 2001 / 2003 chip found in all official WonderSwan Cartridge. It will ultimately provide a fully functional clone of the Bandai chip.

License

This project is currently licensed under the something close to the CC BY-NC-ND:

What does that mean:

  • The BY is the same as the CC:
    • You have to give credits if you are using this code in a chip on your board,
  • The NC differ from the CC:
    • You can use this code to program your own CPLD/FPGA
    • You cannot sell directly this code or a chip using this code, but work using it is fine:
      • You can build your own cartridge that use this CPLD/FPGA (and you can even sell them!)
      • But you can’t program CPLD and sell them directly
  • The ND also differ:
    • You are welcome to propose patch for supporting another CPLD/FPGA or correct bugs, add functionality (you can create fork on GitHub for this is not a problème)
    • But changes in the code to integrate into a more complex COLD/FPGA project is not authorised.

If you have any doubt, please contact me I will be happy to help you
