Guessing by accurate you man playable? The most accurate n64 is https://cen64.com/. It's a cycle redundant emulator made to be accurate. n64 emulation really was the first of its kind and designed to NOT be accurate for limitation of a PC. Actually all emulators really are guesswork, but they do well at what they do. All of this 3d stuff needs a lot of guess work and accuracy is very low priority. It really has all became about game play. PC are getting so powerful now that some accurate emulation is getting focus. If you want to see how an emulator runs without all the guess work, check in a MiSTer sometime. It will take you back like you had no idea what consoles were like, with memories you thought you lost. For example, I remember playing Zaxxon at the arcade long a go and have played the Mame arcade Zaxxon a dozen times on PC. Yeah, I remember it, loved it, still do... I recently ran a Arcade MAME set up to try it out. After loading Zaxxon the sounds just took me back to childhood. All of these memories of smells, things, people, and music just rushed back to me like it was 1984. The sound for the emulator was so perfect it just rushed my body with chills. Anyways, my point it that emulators do not really do much in the way of accuracy. That is always second to next. No, PJ64 is not accurate.... Playable, but not in anyway accurate.
