This project represents a community-driven effort to provide an easy to build and easy to modify cartridge dumper.
Happy making. 🔧🔨😊

And be sure to check the guides in the Wiki too.



  • Completely stand-alone, does not need a PC to operate (unless for updating firmware)
  • Easy to modify open-source code, write your own extensions and share them with others
  • Portable thanks to a battery/power bank
  • Modular design using mostly off-the-shelf components


Supported Systems:

  • Reads official NES, Famicom and Family Basic cartridges including save
  • Supports Mapper 30/NESmaker and flashes INL NM30 boards
  • Reads SNES roms and reads/writes save games from and to the SNES cartridge
    Supported cartridge types so far: LoRom, HiRom, ExHiRom, DSP, SuperFX, SuperFX2, SDD1, CX4, SPC7110, SA1 (last two chips need Adafruit Clock Generator)
  • Reads and writes SNES Satellaview 8M Memory packs (BS-X cartridge and Adafruit Clock Generator needed)
  • Reads and writes Nintendo Power Super Famicom Memory Flash Cartridges (needs Adafruit Clock Generator for best result)
  • Reflashes some Chinese or custom-made SNES repros with AM29F032, MBM29F033, MX29LV320 or MX29LV640 flashroms
  • Reads N64 roms and reads/writes save games(4K/16K Eeprom + Sram + all 3 types of Flashram), Eeprom needs Adafruit Clockgen, Proto carts are not supported yet
  • Reads and writes N64 controller paks and also can test a N64 controller's buttons and thumbstick
