4.0 and Save Extractor/Installer

Since the release of menu 4.0, I've been debating doing the update since the new SD menu is a nice addition and I already have HBC installed, etc. My only concern is what I saw today on the wiki for 4.0: "Affected: Copy protected save files (On SD card); Effect: Save files that have copy protection, that were copied to the SD card through any previously patched system menus, will NOT copy back."

What exactly does this mean? Does this make Waninkoko's Savegame extractor and installer useless after the update or is this referring to another method that I may not be aware of? The reason I ask is because my girlfriend has been editing her Animal Crossing save with the Town Edit tool for PC which requires the saves to be transferred back and forth via Waninkoko's tools.

Can anyone shed some light for me just to be sure? Thanks!

i think it was useless since 3.3v2, but it would be worth a try

Hmm, sorry, I wasn't aware of this. Guess I'll try updating another Wii whose owner doesn't care about homebrew to test it first. Thanks for the info!
