You can get a precompiled build from its topic on the Wii U Hacking section!
It's mainly of interest for Vwii users (which reads the titleid to figure out the original platform: LULZ -> L = Master System and helpfully forces 4:3 video)
So this new version actually resets the video mode when launched (the fact the titleid was also changed to OHBC is not part of this fix, just so that you can have both installed as some homebrews stupidly try to exit by launching LULZ instead of using the generic return-to-loader function)
