Play SNES Games in OS X Mountain Lion with the BSNES Emulator
Super Nintendo was one of the greatest game consoles of yesteryear, and with BSNES you can play the SNES classics right on your Mac running OS X Mountain Lion and OS X Lion. It may not be as full featured as the popular SNES9x alternative that works only on older versions of Mac OS X, but it’s still pretty good and is more than adequate if you’re itching to jump into some retro gaming (you’ll need to find abandonware game ROMs elsewhere).
For the best appearance, open the games Preferences and look under “Video” to make some adjustments. Setting the “Effect Size” to “2x” and “Effect Type” to “Super 2xSal” smooths the onscreen elements and lets you size the window a bit larger, resulting in much better looking gameplay. Regardless of your settings you’ll be stuck with a square playing window that can’t be stretched horizontally.
As usual with emulators, the worst part is the keyboard controls, which are always awkward and take some getting used to. Below is the default layout, it can be customized by clicking and dragging on the buttons you want to switch to different keys.
If you have a USB game controller you’ll probably want to configure it and use that instead, though with BSNES that will require the addition of a third party tool called Emulator Enhancer.
Technically BSNES will run on older versions of OS X too, but SNES9x is generally a better emulator if you’re running a past version of Mac OS X that supports it.
