 ### "WiiVC" Version
 This version isn't really supported much due to the niche nature of it. It enables DRC (Wii U GamePad) support, and also takes advantage of unlocked CPU multiplier support if enabled. The gist of it is that you can run Wii64 on a Wii U in "Wii mode" but with Wii U Game Pad support and (optionally) the CPU multiplier unlocked. To boot this version you can either just use the vWii mode to use the GamePad, or to unlock the CPU multiplier you'll need to be well versed in Wii U homebrew setups (essentially there's a process that exists to inject homebrew into a WiiVC title - e.g. Wii titles were available on the Wii U via the eShop) and there's a thing called [sign_c2w_patcher](https://github.com/FIX94/sign_c2w_patcher) that you must boot before loading this title to unlock the CPU multiplier. This version is shipped as "Wii64 | Rice GFX | WiiVC" and "Wii64 | glN64 GFX | WiiVC" in the archive.
