Overview

Dendy is a free NES/Famicom emulator written in Go, with desktop versions for Windows, macOS, and Linux and a WebAssembly version for modern browsers. The desktop program has no graphical interface and runs from the command line with a .nes ROM file. Player one can use a keyboard or a detected gamepad, and a mouse can emulate the Zapper light gun. Options include save-state control, rewind, screenshots, CRT effects, and Game Genie codes. Network multiplayer uses rollback networking and peer-to-peer connections. A public relay can help players behind NATs find peers and connect, though it will not work if both players are behind symmetric NATs. Users can also build and run their own relay. The browser version does not currently support netplay. The maker cautions that Dendy may not match established emulators in accuracy or compatibility, so some games may not run. Sound emulation is still in progress and may produce pops and crackles. The project is MIT-licensed.

Who it is for

Dendy suits NES/Famicom players comfortable launching a command-line emulator. It may also suit players seeking peer-to-peer multiplayer, provided they account for its compatibility and relay limitations.

What is good

  • Free, MIT-licensed project.
  • Supports rollback netplay on desktop.
  • Includes save states and rewind.
  • Runs in modern browsers via WebAssembly.

What to know first

  • Desktop version has no GUI.
  • Browser version does not support netplay.
  • Some games may not run.
  • Sound emulation may produce pops and crackles.

Verdict

Dendy offers command-line NES/Famicom emulation with desktop netplay and useful playback options. Its maker explicitly cautions about game compatibility, and browser users do not get netplay.
