Nestopia is a Nintendo NES emulator for Mac OS X. Nestopia is by far the most compatible of any NES emulator for Mac OS X. Using cycle-exact emulation, it is able to run titles that rely on precise timing, and which therefore break under other emulators. It supports five extra sound chips and an astonishing 143 mappers. This accurate emulation comes at a cost; Nestopia requires an 800MHz machine for full speed; but if you have one, this the best available NES emulation for Mac.

Nestopia was initially developed for Windows by Martin Freij. The original sources may be downloaded from the Nestopia home page. The toolkit used to more...

I'm new to emulators, and I don't even know if this should be under troubleshooting, but how do I download games to go on it? Thanks.

Works great on MBP Lion, although the controls are not adequately explained. Also, some features are intentionally excluded and sold as a separate shareware add-on.

does anyone know why the game genie codes for legend to zelda worked for the first few hours of the game but now will not work??? have re-entered them correctly a million times,restarted game,loaded saved states etc. still they dont work anymore. where is the data stored for the game genie function to work??? i emailed the developer but he doesnt why. is it bc of lion 10.7.4?? but if that was the case why the hell ddid everything work perfectly and i mean everything in unison,the controll/joystick with emulator enhancer demo,game genie codes,freeze/load states,everything was working perfectly before. i unistalled and reinstalled completely and still same problem. its either the rom itself or nestopia.

A great NES emulator. Provides state freezing/unfreezing, custom keyboard maps for two players, and several other features. I've noticed some occasional stuttering and on rare occasions when opening a ROM it instead opens the previously opened ROM. No significant problems or crashing.

I was wondering, is this a more up to date or renamed version of RockNES?

The current version of Nestopia features

* Completely free to use.
* Efficient CPU usage, for improved battery life on PowerBooks.
* Flexible video display sizes with numerous Blitter effects.
* Sound recording functionality.
* Transparent decompression of GZIP-compressed game files.
* Support for 174 different mappers.
* Support for five additional sound chips.

It is THE BEST cycle-exact emulator for NES on OS X.

The previous reviewer who said Nestopia can't run full screen stated falsely. The free version of Nestopia cannot run full-screen; with the purchase of Emulator Enhancer (which works with ALL of Bannister's 28 current emulators).

From his web site:
Additional Features

This feature set above can be expanded using Emulator Enhancer, a shareware module which adds the following additional options:

* Full screen mode.
* Network play (some emulators).
* Real time video and sound filtering.
* Support for USB game pads and joysticks.

EE is currently available for . If anyone wants to rate EE (based on the customer having to pay for it), this belongs in a review of that software, not Nestopia.

Nestopia even has its own support forum now; use it if you need help with the program: http://www.bannister.org/ubb/ultimatebb.php?ubb=forum;f=36

I rated the Features as low, as Nestopia is missing a few features in the free version -- also, it is currently missing support for zip and 7-zip archives, as well as for Quartz effects and OpenGL overlays.

Everything else, I rated as 5, as there are no other NES emulators that perform as well (on ANY platform) as long as you have a fast enough CPU to run it at full speed.

The best Nes emulator available for the Mac. You need emulator enhancer to make the best of all of Richard's emulators but its a small price to pay for all the hard that one person has done porting so many emulators to the mac.

The emulator gains support from the developers "Emulator Enhancer" product. This adds full-screen support and gamepad support. Emulator Enhancer is shareware, but is fully-featured without registration (there is a nag screen at startup).

The best NES mac emulator. SO the best. I don't like NES much but I play it now just because this emulator is better than my N64 one!!!!

Get this emulator, and get commercial ROMs for it with Limewire a free program that lets you download files
