Problems with WarioWare D.I.Y in TWiLight Menu++

I dumped my copy of WarioWare and, if I provide a save file, it boots just fine into TWiLight Menu, but it used to store games and now it doesn't. It's not erasing everything, mind you, only the games. I've heard that it might be the way the game saves, but I stored at least one game earlier and I was able to dump it with miotool, so I know it can, it just stopped. I didn't update between the problem starting and now, it just sort of happened. I did try the latest patch this morning, but that didn't work either. Also, I can't get cheats to work and I can't start a new save using TWiLight Menu's built-in save slots, so if its an anti-piracy measure, I can't use the AP cheat to bypass it. Any help that anyone can offer would be appreciated.
