reminder once again if you have a 3ds or wii u to dump the spotpass data on it: https://spotpassarchive.github.io/
just looked at the spreadsheet and there are quite a few common 3ds titles with incomplete data, but that's nowhere near as much as the wii u list which shows a large majority of titles as having incomplete data
we only have until april 8 to archive everything, the link above has guides for both modded and unmodded systems
there is now a method for unmodded wii u systems, just put in an empty sd card and open the website mentioned in this guide on the web browser: https://spotpassarchive.github.io/guides/wup/browserhax
