The N64 certainly wasn't the most successful games console, but it still generated a certain following, hence why emulators like Mupen64 can be found.
Thanks to Mupen64 you'll be able to load and play any N64 ROM on your Mac. The emulator is relatively easy to use and you'll find a readme file that comes with the download indicating the button configuration.
From the preferences you'll be able to choose from one of four resolutions, which is a good thing as Mupen64 first launches at a resolution of only 320*240. The application offers three texture cache size and you'll be able to activate fog, fullscreen, and both 2xSal and Bilinear filtering. From the options menu Mupen64 also allows you to limit the speed of games, set the audio and choose from three emulation cores. You'll have to restart the emulator for changes to come into effect though.
Mupen64 is said to work with plugins, but we could not find any sign of them anywhere in the program.
The configurations are a little counter-intuitive, yet if you stick to launching ROMs you'll find Mupen64 is a good emulator for enjoying N64 games.
