Game and save dumper, reverse engineering tool, in system debugger, and cart flasher all in one!

CopyNES is the most versatile hardware NES tool. This updated USB version avoids parallel port compatibility problems and runs at the maximum speed for the system. After soldering the board inside your NES system and connecting to your computer you can:
  • Dump NES games and Famicom (with pin adapter) games
  • Dump and rewrite saves
  • Reverse engineer games and mappers
  • Test and debug your homebrew on the system with a flash cart
  • Flash Glider, PowerPak Lite, UFROM, NSF, and RAM carts
  • Fix Game Action Replay carts after replacing the battery


    • CopyNES is a fully DIY tool. Installation requires soldering, desoldering, and hole cutting on an original front loading NES system. For best results you will need at least basic knowledge of NES mappers, boards, and NES programming.

    Works on NTSC and PAL systems. Software requires Windows OS, see links below. Protocol and drivers are public so others can write Win/Linux/MacOS clients.
