Dolphin is a Gamecube and Wii emulator. Most games run perfectly or with minor bugs. Games are playable at HD quality, with 1080p and more. This is a remarkable feature the actual Gamecube and Wii consoles are not capable of. As an open source project everyone can commit improvements. The code is hosted on code.google.com. Dolphin is actively developed and almost every day new features are added and bugs fixed as well. Dolphin is a multiplatform project and many operating systems are supported. Dolphin runs on Windows 7 (x86 and x64), Mac OSX andLinux.

FCEUX is a Nintendo Entertainment System (NES), Famicom, and Famicom Disk System (FDS) emulator. It supports both PAL (European) and NTSC (USA/JPN) modes. It supports both Windows and SDL versions for cross compatibility.
The FCEUX concept is that of an "all in one" emulator that offers accurate emulation and the best options for both casual play and a variety of more advanced emulator functions. For pro users, FCEUX offers tools for debugging, rom-hacking, map making, Tool-assisted movies, and Lua scripting
FCEUX is an evolution of the original FCE Ultra emulator. Over time FCE Ultra had separated into many distinct branches.
The concept behind FCEUX is to merge elements from FCEU Ultra, FCEU rerecording, FCEUXD, FCEUXDSP, FCEUXDSP CE, and FCEU-mm into a single branch of FCEU.
As the X implies, it is an all-encompassing version of the FCEU emulator that provides the best of all worlds for the general player, the ROM-hacking community, and the Tool-Assisted Speedrun Community.

Highly-Experimental Playstation Simulator for x64 based systems. This is a WORK IN PROGRESS.

Jnes is a NES emulator for Windows and Android platforms.
 
Its emulation capabilities include graphics, sound, controllers, zapper, and many memory mapping boards found in most USA games and a few popular Japanese boards adding international delight. Jnes boasts an intuitive user interface with instant saves and movie recording to making playing NES games more enjoyable. One of the coolest features is the included database of Pro-Action-Replay and Game Genie cheats, courtesy of Gent.
 
Jnes supports Kaillera for online gaming. There is also a forum at Emutalk for talking about Jnes with a larger community of users.

MoarNES is an emulator for the classic Nintendo Entertainment System video game console. It is relatively new, and currently still in alpha. It is being continuously worked on an improved with the goal of being among the best NES emulators available. Is it there yet? Not quite, but it's a very useable and fairly compatible emulator still at this point. It is written from scratch in C, with no code taken from existing NES emulators.

This is the Windows release! For Linux or Mac, please visit the official website.
 
Mupen64Plus is a cross-platform plugin-based N64 emulator which is capable of accurately playing many games. Included are four MIPS R4300CPU emulators, with dynamic recompilers for 32-bit x86 and 64-bit amd64 systems, and necessary plugins for audio, graphical rendering (RDP), signal co-processor (RSP), and input. There is 1 included OpenGL video plugin, called RiceVideo. There are 3 other excellent video plugins being maintained by wahrhaft, called Arachnoid, Glide64, and Z64.

My NES is a portable, open source, low level NES/Famicom emulator written in C#. The compatibility of My NES is very high, running most games without any bugs. The aim of the project is to reproduce any hardware quirks that games may rely on as elegantly as possible. May NES doesn't employ any game specific hacks or hash checks (Aside from filling in pot holes left behind by the iNES file format).

NESten actually started as a fruit & vegetables emulator. Titled M.U.R.D.E.R
(My unnamed rodent didn't eat rice), this was a test to see how long it would
be before cavities would develop in the human mouth. Actually, wait, no. The
term "NESten" is a Norwegian word for "almost". Therefore, NESten is "Almost
NES". Get it? Didn't think so.
 
The project began as a test to see how well emulation of the NES could be
done in Delphi. Amazingly enough, the emulator can run full speed on a P166
MMX (with sound enabled, a decent video card is recommended).
 
If you don't like the emulator, you're welcome to try out other emulators,
such as N'tendo, iNES and Pretendo.

Nestopia is an open source NES/Famicom emulator written in standard C++, focused on delivering as accurate emulation as possible. Development began in mid 2002, initially released for the Windows platform a year later. It has since been ported to other platforms, including Linux and Mac OS X.

Nestopia is an emulator for the Nintendo Entertainment System/Famicom (and Famicom Disk System). It is a computer program that acts like a physical piece of hardware. In other words, this is a method of preserving videogame history, with the welcome side effect of allowing you to play NES games on a modern computer.

Nintendulator started out as NinthStar NES, written by David "Akilla"
De Regt. Written in C++, it was a reasonably accurate (and slow) NES
emulator which used NESten 0.61's mapper DLLs. Numerous other systems
were planned to be emulated within NinthStar (as well as complex
debuggers for each of them), but somewhere along the line, the project
was abandoned.
 
At that point, I took the existing NES sources and started improving
them. First, the PPU was rewritten to be much more accurate than
before, running cycle-by-cycle according to documentation that had been
released at the time. After that, the CPU was rewritten to execute
instructions more accurately. Then the APU was mostly completed, giving
the emulator proper sound. Somewhere along the line, it was determined
that the C++ usage in the code was very poorly done and was slowing the
program down, so I converted it to plain C and named the program
"Nintendulator".
 
The eventual goal of Nintendulator is to be *the* most accurate NES
emulator, right down to the hardware quirks. In the meanwhile, it can
certainly be used to test NES code with confidence that if it works
properly in Nintendulator, it will probably work properly on the real
hardware as well.

NO$GBA (pronounced "no cash GBA") is a free Nintendo DS and Game Boy Advance emulator for Microsoft Windows & DOS. It is capable of running commercial and homebrew Game Boy Advance and Nintendo DS ROMs, many at full speed. It is the first Nintendo DS emulator running commercial ROMs. However, this claim has been disputed by many in the emulation community. NO$GBA was developed by Martin Korth.

nocash PSX emulator/debugger for windows
 
The Program is intended to work out-of-the-box. There is no need for specific windows versions, special video drivers, obscure plug-ins, virtual CDROM drives, system BIOS, or tweaked per-game configurations.
 
The Emulation should be complete with all hardware features fully implemented and working, though as by now it wasn't tested with too many games, so there may be still some problems with other games (bug reports are welcome).
 
The BIOS is emulated via a BIOS-clone, which is free and faster than the original PSX-BIOS. There may be still some compatibilty issues (especially as most PSX games are applying patches to the original BIOS; the BIOS clone is reproducing known patches, but may fail on unknown ones). In case of problems, please use a copy of the original BIOS (with filename PSX-BIOS.ROM in no$psx folder), and please let me know if that is fixing problems with any games.
 
CDROMs are supported via complete disk images (in .CCD+IMG, .CDI, .CUE+BIN, .MDS+MDF, or .NRG format), via single-track images (.ISO files), or as raw executables (.EXE files). Decompressing .ECM and .CDZ files is supported. Subchannel data (for libcrypt'ed games) can be read from .SBI, .M3S, .SUB, .MDF files. Reading from real CDROM drives is also supported, but does require wnaspi32.dll (which appears to be a problem on WinNT/Win2K and higher).
 
Minimum Requirements are around 1-2 GHz on a Pentium 3, which is maybe fast or maybe not so fast (older PSX emulators are said to be working on 200MHz computers, on the other hand, I got told that no$psx is much faster than those old emulators... I've no clue how that is possible).
 
Debugging/Development functions include disassembler, debugger, profiler, code breakpoints, memory breakpoints, assembler, I/O map viewer, VRAM viewer, polygon viewer, TTY debug console window, and complete PSX hardware specs.
 
Pocketstation is emulated as part of no$gba v2.7 and up (the pocketstation is a PSX memory card with LCD screen; emulated in no$gba because GBA and pocketstation are both based on ARM processors).

The emulator has been temporarily removed from our download database, as it has been flagged with a virus. We have double checked with the developer's website and confirmed that it's an issue on their end. Until the emulator is re-released clean, the download will be unavailable here on 1Emulation.
