I found out today that Xevious was released on Nintendo Wii U. Can we have that added as a console?

More specifically, it would be Wii U VC.

I added WiiUVC platform. WiiUVC version is an emulation of NES version, so WiiUVC version is applied the same rule of NES version.
When the players request, I'm willing to add other platforms. Xevious has many versions on many platforms as far as I know. It is not realistic that we note all of their rules in "Game Rules".
So now we have the policy as I said above.

It looks like it’s on Switch now as well, as part of this collection: https://www.nintendo.com/games/detail/namco-museum-archives-vol-1-switch/

I added Switch platform. Switch version is an emulation of NES version.
I don't want you to request adding another platform if you are not going to submit runs on it. Xevious has too many portings. We become not to be able to control this category.
