Yeah, Really the only reason i purchased mine. Wanted to get one before Nintendo patched it up. For now i got everything i need to hack the vwii, and play some emulators/gamecube/wii games.
I also saw someone on Reddit a few days ago that got the MK8 + DLC bundle and had 5.5.0U as well. I made sure tubehax was setup during the initial setup to make sure it doesn't update. Your best bet would be track down another bundle.
