Help / Q&A

For any questions related to this project, please use Discussions tab in GitHub repository. Do not use my e-mail for these questions, as I want to have a centralized knowledge base accessible for everyone interested in this project.

I'm also active at N64brew Discord server as korgeaux#5558 but keep in mind that Discussions tab is a preferred option.

Acknowledgement

This project wouldn't be possible without these contributions:

  • 64drive orders being on permanent hold long before creating this repository.
  • EverDrive-64 X7 being disappointment for homebrew development (slow USB upload, unjustified price and overcomplicated SD card access).
  • Jan Goldacker (@jago85) and his projects:
    • Brutzelkarte providing solid base for starting this project and sparking hope for true open source N64 flashcarts.
    • UltraCIC_C reimplementation for easy integration in modern microcontrollers. Thanks also goes to everyone involved in N64 CIC reverse engineering.
  • N64brew Discord server community being very helpful during flashcart development.
  • FatFs FAT32/exFAT library being easiest to integrate in embedded environment.
  • Yakumono's (@LuigiBlood) extensive 64DD documentation and its implementation in various emulators.
  • Libdragon open source N64 SDK project and its developers.
