Updated!
Now provides quick-HBL and haxchi, in addition to the newer hbas. As with the previous
wiiubru.com/go the SD card only needs to be FAT32 formatted. Nothing on the SD card needs to be set up ahead of time to launch any one of these.
Honestly, I still get pretty slow download times, but I'd expect the download times in Europe to be faster.
It would be nice to have an all-in-one URL-based installer, but for now, hopefully the flexibility offered by wiiubru.com/go is a nice alternative for people who want to be able to setup their Wii U without a computer.
