CEN64 vs Not64

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.

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.
