This release is essentially identical with the upstream fail0verflow version, save for its Title ID which has been changed back to LULZ to allow for use with BootMii and other older homebrew that isn't OHBC-aware.
For Wii mode on the Wii U (vWii) I recommend using OHBC version 1.1.4 from fix94 as it contains some vWii-specific features like Wii U Gamepad support.
For normal use, install the provided wad. The other options are only here in case someone needs them.
