Gopher64 vs Wii64 / Cube64

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.
