True to its name, the GUI of the patcher is unhinged. Instead of a standard gray window with "Browse" and "Install" buttons, the R2RWaiFu tool features an animated anime girl (the "Waifu") who reacts to your mouse movements.

Updates to how the emulator handles digital signatures and certificates, making the "cracked" software indistinguishable from the original to the host OS.
