Can I play Project M on the latest Wii U upgrade?

On the latest Wii U upgrade they took off the Wii menu.
As far as I know, the Wii menu was significant to make Project M work, then, PM still works on the Wii U?

On the latest Wii U upgrade they took off the Wii menu.

I'm pretty sure that's not happening, since that's the system's primary way of running Wii software.

In any case, Project M may be run from within Brawl itself (a.k.a. the "hackless method"), which they can't patch, so no, such an update does not completely prevent you from accessing Project M.

If your Wii menu does appear to be missing, check all pages of the Wii U menu. If it's not there, you may have received a faulty update, and should probably contact Nintendo for support.

Indeed. The disc itself is hacked, so there's no way any kind of patch could fix that.
