Hi DiggerandIndy,
Wii Longplays should be submitted in 720x480, 480p if possible.
One of my friends used his WiiU to record a Wii Longplay namely Pikmin 1. He recorded it in 720p60fps.
Link to his Longplay on WoL and YT:

When the new site hits soon hopefully we should be able to make new guides that are a little more updated.
