Nintendo Wii U Emulators

About the Nintendo Wii U and Wii U Emulation

Nintendo Wii U EmulatorsThe Nintendo Wii U is an eighth-generation video game console and the successor to Nintendo’s insanely successfully Nintendo Wii. The console was released to the world in 2012 but sadly lacked the massive amount of hype and excitement that its predecessor had created, this was not helped by a fairly lacking library of launch day games.

The Wii U was a primary competitor to Microsoft’s Xbox One, and Sony’s PlayStation 4, sadly though despite those consoles releasing nearly a year after the Wii U’s release, the Wii U just couldn’t make the same level of sales, its hard to say whether this was due to a lacking library of games or poor marketing, the name Wii U may of created confusion with some consumers due to its similarities with the Wii name.

Wii U emulation seemed to be something that was never going to happen for a period of time, over the years there was a few attempts here and there that attempted to emulate it but most of those projects were short lived or ran into problems due to the sheer lack of documentation on the inner working on the Wii U. It was not until October 2015 when there was a big breakthrough in emulation, and a massive surprise to the emulation community and that was with the first release of Cemu. Cemu was the first Nintendo Wii U Emulator that started showing real promise. Despite Cemu being closed source there is now another promising emulator that is making progress, namely the open source Decaf emulator project.

The biggest hindrance to the Wii U over its competitors is down to its poor library of games, not only was Nintendo incredibly slow in bringing there own superb IP’s to the console, many 3rd party companies simply abandoned the console altogether leaving it with a void of games despite some superb surprises like Bayonetta 2.

Decaf Emulator – Decaf Emulator is the only open sourced Wii U emulator around, so far it isn’t as advanced in its emulation of the Wii U as Cemu is, but it is making remarkable progress.

Cemu – Cemu was a surprise Nintendo Wii U Emulator, and so far has been the most successful one, in just over a year it has gone form just being able to boot games to being able to run several games without any game breaking hitches.
