1964 - An open source emulator and long-time competitor to Project64.It is one of the best emulators for general use, with good compatibility with most of the popular games. The interface is slightly clunkier, and switching between RSP plugins is a pain (the desired RSP plugin must be named rsp.dll for the emulator to see it and use it), but timing issues are less severe, it has a more up-to-date RDB at the moment, and many of the later improvements were ported back through Jabo's 1.6.1 patch. Project64 1.6 - The older but more stable version.

Still, for general use, it might be wise to stick to either Project64 1.6 or Mupen64 for the time being. It also fixed a number of games that were completely broken in 1.6, such as Kirby 64. However, the user interface is quite a bit nicer and easier to use, and switching between RSP plugins is far easier than in 1.6. Some users have also reported problems with BSODs, which apparently may be an issue with outdated Windows system files.

Its RDB is somewhat outdated, and some games have issues with audio and timing regardless of plugin setup unless you mess around with timing settings.

Project64 2.3 - The most recent version of Project64, now public and open source (though the official download asks you to install useless toolbars).
