Aaaaand it worked! Changed the Title ID version number as well as all the Update version numbers (I noticed that all three JPN USA and EUR versions were listed with v112 [1.3.1]) and reverted everything back to v97 (1.3.0) ! Of course I had already deleted the update data on my Wii U and installed the old update data that was still on my SD Card from when I had the card prepared by Wii U USB Helper awhile back. I was afraid my save file wouldn't load since I saved on v112 (1.3.1) without knowing about the update all this week, but I successfully loaded my save file on v97 (1.3.0) just now! Infinite item glitch, here I come!!

So i changed the Version in the slc/security/versions.bin file, but it's still not working. Where is the Title ID version number you're talking about?
