Cemu is the first eighth generation console emulator in the world, specifically the Nintendo Wii U. The requirements are big - at least efficient Core i5 and 6 GB RAM, Nvidia graphics card or AMD with support for OpenGL 4.0 (and if possible, OpenGL 4.5), 64- Windows bit (7, 8.1 or 10).
In return, we get the ability to run games smoothly even in 4K resolution (although it is better to have 1080 Ti). Also DRC (GamePad), Pro Controller and Classic Controller controllers are emulated, the keyboard and USB controllers are partially supported.
