You'll have to install the Microsoft Visual C++ 2017 X64 Redistributable: vc_redist.x64.exe from http://cemu.info/ again, but yeah, thats it. If you have any change to the cemu.exe file you'll have to also do it again. Source: 12 months ago

You download Cemu yourself from https://cemu.info and follow the Cemu setup guide from https://cemu.cfw.guide/. Source: about 1 year ago

If you hop on over to r/roms though they have a pinned megathread which links to trusted sources (often on a site as reputable as archive.org). Grab the Tekken Tag Tournament 2 Wii U Edition .wua from here and run it on CEMU instead of trying to locate the PS3 version. Wii U emulation is much further along so this will run better anyway and CEMU doesn't require additional BIOS for setup iirc. Source: about 1 year ago

CEMU has an official site you download the emulator from: https://cemu.info/. Source: over 1 year ago

Using latest Stable (1.26.2f from https://cemu.info/), in Desktop mode, Options > Graphics API set to Vulkan, Async Compile enabled, vs 3 CPU, it's 60FPS like 99%+ of the time, with a slight hitch now and then when something 'new' is loaded/shown. Source: over 1 year ago

The closest modern equivalent is the Keymouse Track and it's awesome. Source: 12 months ago

A somewhat more obscure, and fairly spendy option, is the KeyMouse. Each half has an optical sensor built into the bottom, and they also have trackball versions. Source: about 1 year ago

Well, there's the Keymouse which is a split keyboard with a mouse sensor under each half. That had quite a long development period - IIRC it was going to have smaller keys with Cherry ML low-profile switches so it wasn't too huge, and lots of people in here complained and asked for MX regardless of size.
