RockNES 4 has been removed at the request of Richard Bannister, its author. He recommends you use NesTopia instead.
RockNES 3.1.3. This is the last "fast" version of RockNES for OS X. It is not cycle-exact. The link has been removed by request of Richard Bannister, its author.
RockNES Classic 2.4.0 for all PPC Macs. The link has been removed by request of Richard Bannister, its author. It is available from the mac-emu.net archives.
RockNES supports a plethora of mappers, including the FDS DiskSystem, and has excellent sound support. Richard Bannister decided to stop updating the Mac OS port of RockNES due to personality differences with the original creator. Because of this and the fact that RockNES is not open-source, the Macintosh version of RockNES may not ever see another update.

| Nestopia 1.3.7. Requires Mac OS X 10.4. |
| the source code to Nestopia 1.3.7. |
Nestopia is 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.

| iNES 1.2. |
iNES features a highly optimized PowerPC assembly core, which allows it to run at full speed on even the slowest PowerPC-based Macintosh! iNES also has excellent compatibility with most ROMs and DiskSystem titles with almost no glitches. (The sound could use a little improvement, however.) This update features improved video emulation, and smarter mapper handling.

| the source code to Graybox Z. |
GrayBox is an open-source NES emulator for Macintosh. Designed in PowerPC assembly, GrayBox is very fast, supports several common NES mapper types, and has very good sound emulation. GrayBox Z was an attempt to redesign the architecture of the emulator and improve compatibility, but it never got very far along in development. GrayBox and GrayBox Z have both been discontinued.

macFC is another Nintendo emulator with great compatibility. MacFC is a necessary addition to your emulator collection because it offers light gun support, Family BASIC support, and it also tends to be very good for playing hacked games that won't run in Nestopia or RockNES.

| NESMac 0.3.6a4 for PowerPC Macs. |
| NESMac 0.3.6a4 for 680x0 Macs. |
NESMac is a Nintendo emulator which only supports games with small cartridge sizes (mapper zero) at present; however, the games that it does emulate run quite well. Although this is a very early release, sound is supported, and games without scrolling seem to run without any glitches.

| TileEater for PowerPC, version 1.0.1. |
| TileEater for 680x0, version 1.0.1. |
TileEater lets you edit the graphics of an NES ROM file. It supports workspaces, palette swapping and an easy-to-use interface. If you ever thought it would be cool to hack NES ROMs, now's your chance. Note: you must open NES ROMs with the File menu. If you just drop a ROM onto TileEater's icon to open it, you will not be able to save your changes.
| NESRomTool for Mac OS X, version 0.61 |
NESRomTool is an NES graphics editor similar to TileEater, except it runs from a Mac OS X terminal.
