Not64 vs OpenEmu

Not64 is a free, experimental Nintendo 64 emulator for Nintendo GameCube and Wii, described as a modification of Mupen64GC using devkitRice. It accepts z64, v64, and .n64 ROM files of any size. For SD or USB storage, ROMs go in /wii64/roms and saves in /wii64/saves; ROMs may also be anywhere on a DVD, with DVDxV2 required for Wii disc loading. Input supports Wii Remote, Nunchuk, Classic Controller, and GameCube Controller, with up to four Wii Remotes. Buttons are configurable through four slots for each controller type. Users can select a pure interpreter for compatibility or dynarec for speed. Video settings include aspect-ratio selection, forced 16:9, and optional 2xSaI texture scaling. Automatic native-save loading and saving and save states are supported, while save copying and deletion are not implemented. Downloads name Wii, Wii Mode (vWii) on Wii U, and Wii Mini. The project uses GNU GPL v2, with similar licensing and source availability required for released modifications.

OpenEmu is free, open-source video game emulation software for macOS. It organizes game backups into a unified library, adds box art and supports collections spanning consoles. Users drag and drop backups for scanning and organization. Modular cores from open-source projects emulate systems including Atari, Game Boy, Nintendo, Sega, Sony PlayStation and Super Nintendo; the project lists 31 supported systems. Generic HID-compliant USB or Bluetooth controllers can work immediately, with automatic mapping for recognized devices. OpenEmu is intended for games users already own, and BIOS files are required. The wiki describes an experimental arcade core plugin that is strictly unsupported. The latest release page identifies OpenEmu 2.4.1 binaries as Intel-only. The official site offers a macOS (OS X) application, but the version requirement was not rendered. The project lists save states, CD audio and cheat support, while online netplay is not available.
