Dendy vs FCEUX

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.

FCEUX is a free, open-source emulator for NES, Famicom, Famicom Disk System, and Dendy systems. It supports NTSC, PAL, and NTSC-PAL Hybrid video modes and offers tools for casual play as well as advanced work such as debugging, ROM hacking, map making, tool-assisted movies, and Lua scripting. The project maintains Win32 and Qt/SDL ports. The Qt/SDL version runs across Windows and UNIX-like systems, including Linux, Solaris, BSD, and OSX. Its tools include debug utilities, movie recording, a TAS Editor, sprite viewer, NES Palette Editor, AVI RIFF Tree viewer, and frame timing tool. Network play in both Win32 and SDL ports is not functional, and the project says it has no plans to fix it. Building Qt/SDL requires Qt5, SDL2, minizip, zlib, and OpenGL; CMake is needed to build from source. FFmpeg libraries are optional for AVI recording, and libx264 is optional for H.264 AVI encoding. The project dates to 2006, and its home page lists version 2.6.6, released on 26 August 2023, as the latest release.
