These are not impossible to figure out, but outside of the scope of what work I'm willing to put in. However I could not get the same calculation working for the Switch save - it would appear some combination of the polynomial, initial value, and final XOR value have been changed (or I'm missing something else, as I only barely follow the maths for CRC calculation). On the subject of the checksums, using the information from Antidote I was able to get a CRC32 calculating correctly for the Wii version. I say sort of because I could get the quantities for materials/bugs loaded correctly by switching to reading data as big-endian I have no idea how that would affect all the other flags in the save file meaning that a converter would first have to thoroughly document every part of the save file on both the Wii and Switch to guarantee a proper conversion.

That being said, I quickly adapted what little editor I had to load Wii files (I had an unencrypted save hanging around in my Dolphin setup, there's also Wii homebrew that will dump unencrypted saves) and it sort of worked. It's not relevant here as we'd only ever be working on the unencrypted save. The only reason the Wii editor needs Wii keys is that it's expecting to work on saves exported to SD cards (not the wiiking2.sav file itself) which are encrypted with an AES key shared between all Wiis. So, I have been tinkering with an editor but hadn't got to the CRC/Checksum issue.
