CEN64 aims to become a cycle-accurate open-source Nintendo 64 emulator for Windows, Linux and macOS that is still in very early development.

One of the emulator's branches is based on Angrylion's MAME video implementation, which is highly accurate, although MarathonMan wants to write his own RDP in the future. The goal is to add additional full-cycle accuracy.

It was rapidly progressing to a usable state and is capable of playing many commercial ROMs with only minor issues. However, due to its extreme focus on accuracy, it will also require good hardware to play at decent speeds. It also lacks dynarec. The emulator does have sound processing but not a UI, although there are already quite a few good unofficial frontends available (like CEN64-Qt).

CEN64 is slightly unoptimized. However, there are reports of people being able to run the emulator at decent frame rates using at least an Intel i5 4670K, and the performance is getting slightly better with each release. MarathonMan is aiming for system requirements on the level of bsnes. Whether or not that's possible remains to be seen.

  • gamax92's "If CEN64 ran at full speed" video series. The CEN64-related videos are particularly interesting. Gamax92 dumped the frames of a select number of games and put the images together into movies to show what the games would look like if there weren't any performance issues. Notice how many of the games shown are almost completely accurate to their console counterparts, save for a few hiccups.
