HAXX

You will need a payload.elf file inside "SD://wiiu/"! Then click "HAXX" and wait.
If it hangs, try deleting your browser save data.
If you get an error, try reading it.

You can download the original JSTypeHax Payload that will start the Homebrew Launcher (needs to be on your SD card) or use Tiramisu (recommended).

JSTypeHax was made by orboditilt.
