And if you want to go full screen and use a USB game controller you’ll need to download and install the add-on, Emulator Enhancer (shareware | $30 | download). It’s fast, precise, and is darn near perfect.
Nestopia (free | download) Nestopia is the current king of the NES emulation hill. I’ve been able to get both up and running with my Gravis GamePad Pro, and both are compatible with the ROMs I use on my PC (I use nesterJ btw). Of the handful of NES emulators available for the Mac, I suggest using Nestopia or Maciform. If you’re one of those folks who want to set up an NES emulator on a Mac here’s what you need to do. It used to be that you could only emulate the NES on a PC, but some crafty developers have made it possible to emulate the NES on a Mac. In fact, I play NES games way more than I do games on my Xbox 360.
I love Baseball Stars, Final Fantasy, Tecmo Bowl, and Swords and Serpents. I love the 8-bit Nintendo Entertainment System.
