Dolphin

Dolphin is a Gamecube, Wii and Triforce emulator that provides users with the possibility of playing their favorite console games directly on a Windows machine.

Intuitive UI, but it requires medium-level configuration

While the interface is pretty user-friendly and straightforward, not the same thing can be said about the configuration menu which makes setting up the application pretty difficult for beginners.
Generally speaking, the main issue when it comes to this kind of software solutions is their efficiency, as many similar tools fail to serve their purpose. Based on our tests, we can say that it works with some games, but we have experienced many titles that simply do not load during our test.
It does not matter whether you are trying to play a Wii or a Gamecube game, you must be lucky to get a title work in Dolphin, and you can't do much about it.
The program comes with multiple configuration screens concerning not only the main application but also graphics, DSP, the Gamecube Pad and the Wiimote.

Provides you with advanced settings to customize the game display

It comes with Xbox 360 controller support, anti-aliasing and anisotropic filtering, a memory viewer and dumper, WAD support, a memory card manager and an action replay simulator.
The main configuration menu allows you to enable dual core support, cheats and idle skipping, but also to juggle with CPU emulator engine settings, such as JIT recompiler, JitIL experimental recompiler and Interpreter.
Of course, a help file is absolutely mandatory when it comes to such a software solution but, unfortunately, Dolphin provides no offline assistance and clicking on the “Help” menu actually gets you to the official page of the developer. Which, in this case, is useless when looking for help.

A Gamecube and Wii emulator that allows you to enjoy your games in HD

All in all, Dolphin remains one of the most effective Wii and Gamecube emulators, even if many of the games don't work at all. The addition of a help file would make it much more appropriate for beginners as well.
