CEN64 vs Gopher64

CEN64 is a free Nintendo 64 emulator for Windows, Linux, and macOS. It aims to reproduce the console by modeling its hardware at the register-transfer level, while optimization remains a goal for eventual full-speed play on modest systems. To run a game, users need a valid NTSC or PAL pifdata.bin file and a big-endian .z64 ROM. CEN64 can also run 64DD disk images with a valid 64ddipl.bin file and an .ndd image. The README documents EEP4K, EEP16K, FLASH, and SRAM save options; users select the save type themselves. A multithread option is available and is described as faster than running without it. Prebuilt executables are linked for Windows and Linux, including a Debian 9 x86_64 Linux build. On macOS, the emulator must currently be built from source, using CMake, iconv, OpenAL, and OpenGL. The project uses the BSD-3-Clause license. An open issue reports an ARM build limitation.

Gopher64 is a free, open-source Nintendo 64 emulator for Windows, macOS, Linux, and Android. It supports homebrew software, netplay, and local or server-based networked multiplayer for one to four players. Graphics options include upscaling and a CRT shader; emulation features include CPU overclocking, cheats, and save states. RetroAchievements is also supported, and enabling it sends some data to RetroAchievements systems. The itch.io listing names keyboard, Xbox controller, gamepad, joystick, and PlayStation controller inputs. Downloads are listed for all four platforms, with Flathub and Homebrew also pointed out for Linux and macOS. The source code is licensed under GPLv3. During online netplay, the server logs the user's IP address and basic session information—the game title and session name—for operational purposes; no additional personal data is collected or stored. The maker links a wiki and Discord, but there is no game compatibility list; game-specific problems are directed to GitHub issues.
