Since N64 emulator configuration can be very, very game specific, it can be nice to just package all the files for an entire instance of an emulator, configuration and all, with a ROM, and treat it like a standalone game.

That said, this emulator, and maybe Cen64, are the only emulators I know of that are "portable" by default. After using it for a while the program starts to display a popup every time you start it, asking that you pay for the program, and it can't be closed for 30 seconds. There were rumours some versions came bundled with viruses. Unfortunately, Project64 itself hasn't followed suit. So you don't have to go digging through old dead forum posts to find the latest versions. Project64 is pretty good as long as you're using windows, and because of the plugin based architecture we're finally seeing plugins on places like github.
