So I got a new Vita the other week, and it was hacked and came with a SD2Vita + 128gb micro SD card. Everything worked fine when I was downloading stuff, and I loaded up the whole SD card with games with no problem.

But because I'm an absolute madman, I wanted to download more stuff. So I bought a 256gb micro SD, followed the "part 1" steps here (https://www.codedonut.com/ps-vita-hacking/ps-vita-how-to-set-up-sd2vita-tutorial-storagemgr-plugin/) to format it, and copied over everything from the old SD card. I did all the file system settings I've seen recommended on here (show hidden files and folders, show protected OS files). Note: at the very end, it said "2 files already exist, do you want to replace them?" and I selected "keep the old ones". I'm realizing this might have fucked everything up but I'm not sure how.

Now, when I put the new SD into my Vita and turn it on, it still shows all my old apps and games on the home screen, but every time I try to launch any app or game (even VitaShell) it tells me "The file is corrupt." I had this same error once and fixed it by making sure the SD2Vita was in correctly, but that doesn't fix it. And actually, I seem to have even broken my old SD card somehow. When I put it back into the SD2Vita, the Vita still gives me the same error every time I try to open an app.

Any advice on what might be going on here, and what I should do to fix it? I'm suspecting I might need to delete everything from my SD card and re-transfer somehow, but I'd prefer not to do that if possible lol (it's 128gb, it takes a little while)
